I recently installed SalomeMeca for Windows and Code_Aster Solver. This was my first simulation to know what are the steps involved in the solution of a basic FEA using an open source software; I used commercial software before. Thanks for this video, Salome Meca is an incredible tool. Keep doing the good work. Greetings from Venezuela.
I did the tutorial on Salome-meca for windows 2023, everything worked very well. Wonderful video, I'm excited to do the other tutorials. I ran Solome-maca 2023 win64 (.bat) and installed Code-Aster 2023 MSI. Thank you very much.
Very well done. Definitely a change from the commercial software that I am used to, but with lots of pausing and replay I was able to get all the way through. A definite must see video for new users.
Very nicely done! I had one issue while watching. When I opened the code_aster module, my mesh was no where to be found. The only file type that could be saved was the *.hdf file which obviously contained no mesh information. My solution was to export the mesh to a MED file before opening the code_aster module. Perhaps I missed some step in the video. But again, you made an excellent video tutorial.
at between 14:00 and 15:50, when I was following you with selecting faces, I also had selecting problems and figured out that the program actually selects the faces at just a click, but it just doesn't put the names visible onto the box and that's what makes us confused. So just don't mind about it and click apply and close..it would work just fine. To make sure of that, you can edit one of the groups of faces after you had done everything, and it DOES print out the name of faces. I had to work on this for like an hour to figure this out, and hope other people who has same problems would be informed of the fact.
The selection of (geometric) LOAD_FACE at 14:57 does not work because you have chosen it before you go "Direct geometry selection". You go "Direct geometry selection" first, the click select the LOAD_FACE.
Dear Cyprien, which is the command if I need to put a node on a specific location? to apply a load, check tension or so on? Thank you for helping, Andrea
Thank you for the valuable video for the ones who are trying to get started with this platform. Of course any additional tutorials will be appreciated :). Cheers
Thanks for your tutorials, they are very useful for beginners like me. Is it possible to model laminated composite structures in Salome Meca. If it is, could you make a tutorial for composite plates, please.
HI, when I finish the setup of analisys step, I set the output setup , then i go to history view, prest th + symbol, and i got a message error , which says: "..Cannot read output file or empty file.." (I have a special partition for acaelinux, running salomemeca vsersion 2019.0.1), what do i have to do PLEASE
Great tutorial Cyprien! I just have began with SALOME for my geometry generation for the continuous casting simulations with OpenFOAM, and your tutorial provided a great starting point for me! Best regards from Austria)
Great video! Just one question, at the end we see, I think, deformation, right? And if I want to see stress? Or the deformed shape? Is it possible? Thanks
amazing tutorial! it will be great if you could do a static or dynamic multibody analysis tutorials as I haven't seen any online...i will try and do one myself and share it with you to make a tutorial video, if time permits both of us
Thank you very much for your videos. Can you let me know the difference between DDL_IMPO (with GROUP_MA = boundary face) and FACE_IMPO? Also the difference between FORMULE and DEFI_FONCTION for defining displacement on a boundary as function of x,y,z?
i have a problem with a thermal non linear model of hydratation heat, i'm trying to model the adiabatic test but i'm having trouble inputing the affinity function, i cant really understand the way in wich that function has to be input. I will apreciate any advice.
Hello Cyprien! Really nice tutorial with detailed explanations! I would like to ask you for your assistance to further use Salome. I would like to get the stresses/strains out of this simulation (reaction forces, etc.) Can you please do a follow up on this matter?! Thank you in advance!
I really appreciate these videos however the real world is sometimes different. As you have said the Salome / Aster suite is rather complicated and some tasks take so many operations to complete. Accordingly I have prepared my mesh in Coreform Cubit (much more efficient) and exported this as a series of .unv files (one file for each group). I have also put the boundary nodes (which I could identify with one line of code in Cubit) into separate .unv files. These all import nicely into MESH but that's when the problems begin. For a start there's no associated Geometry file and all of the geometry related operations are inapplicable. I am finding it very hard to break the mesh into groups for the purpose of applying the BCs and loads and Aster Study doesn't seem to be designed to deal with multiple mesh files. Could you please consider making a video where the mesh is imported, and ideally in more than one file. Even a really simple example, like this plate, would be sufficient to show the necessary steps. Thanks and keep up the good work.
Another question: reslin_DEPL is the displacement, right? I try to create a simple bar with length = 1000 mm and diameter 50 mm, loched at one end and with 1000 N force in the other length. The results that I obtain with salome is very different from that obtained with manual calculation. Of course, I made some type of mistake with salome setup, but what? Thank you
Thank you for the videos. I've number of questions... What about solution verification? Should we reach solution convergence? There is no iterative solver in Salome-Meca?
Hey Cyprien, i m trying to solve a thermo-mechanical problem using salome meca and code aster and i don't know how to do it ! should i run the thermal and the mechanical studies at the same stage or in different stages ? if u know how it works please help me ! THANK YOU

Hello,Cyprin If possible,I want to know how to get von mises stress and displacement simultaneously and how to modal analysis.(This video is only displacement)
I'm also interested in new aster study videos , how get von mises stress ? or other normal stress ? - how salome-meca manages the units of measurement ? - how to perform beam analysis and get the diagrams of moments and internal forces? -how to create a cylindrical reference system and handle constraints and loads with it? -how assig variable surface pressure loads ?
Great Video thank you;) I am a beginner with Salome Meca but I would like to use it with a Matlab optimization loop. does it exist a command to start a calculation directly from the terminal a little like Abaqus with "abaqus job = foo.inp"? Can we act directly on a file like the Abaqus inp with salome / aster?
Hey Cyprien, I did exactly what you did but when I run the calculation an error came up: "Error during submission of "RunCase_1:Stage_1"" , what should I do?
Open le calculation log file. There are generally details about the error. It's either an error in the installation of Salome-Meca (lack of a prerequisite software such as Libopenblas) or a problem in your model. Find the source of the problem and correct it. If you are using the windows version, this version is buggy so I suggest you to install the linux one.
Very nice beginner tutorial. Can you say something to the units? I think, it should be easy, if you have no gravity (and no density). I took mm and N and set E as 210 000 N/mm² The plate is 200mmx200mmx10mm I took a load of 2000N cross (Z-direction) But my results are much to big... (stress and deformation) Why?
Hi Please, sombody knows why when Cyprien Rusu, save the results files the format is "plate2.resu.med" each dot is mandatory? the word resu and med is mandatory, are both reserved worlds? could not I just write a simple name like "myresults" ?
Thanks for the video. So eventually we solved for the deflections as I understand.. are the numbers in "meters"? how can I change units? how can I solve for stresses?
The units aren’t explicitly written. You should try to keep a consistent SI Unit system. For example, If you use “m” as the dimensions of your model, then, your Young’s modulus and all pressure loads defined should be in N.m-2 (or Pa). If model units are in “mm”, then pressure unit would be N.mm-2 instead
@@Feaforall Am I right then, that the plate in this example is 200m x 200m x 10m? I am assuming this because E=2.1E11, which must be Pascal, right? Great video btw!
Hi. Thanks for the video. Do you have video about bugs and errors? I tried to repeat your model and met the problem with solver. It doesn't calculate, I see red circle without error. It's first calculation.
@@Feaforall, Hi, Thanks for your reply. The situation is that I have Salome-Meca ver.9.3 on Windows 10. When I start it, I have next warning: no type found for resource "localhost", using default value "single_machine" When I start calculation of the model ot rounds and when I refresh I see round circle. I don't see any errors and files, only export file. No output files. Regards, Victor
This warning is normal. Maybe that’s a bug of this 9.3 install for windows. Salome Meca is not “officially” supported by the developers. The windows version is built by a 3rd party company without any warranty of bugs or problems. I never tried this version on windows actually and changes are quite big because Salome 9.3 migrated from python 2 to 3. Try to uninstall this version and install the 2018 version (8.6?) which was working fine for me.

Hi, please, somebody help me, I can´t complete any simulation because when I click run this message appears: "Cannot read output file or empty file.". I found some solutions but doesn't work for me
If you are on windows, try to install the latest version of Salome Meca. Also try to remove any blank or space into the path or folder names where you project is saved.
Using C++ and Python you should be able to do that... but you’ll need to develop your own API I think.. there’s nothing ready-out-of-the-box from my knowledge...
Thanks for the upload Cyprien. Very helpful video for beginners, as me! Though, I can't run the analysis from Salome-Meca. I get a UnicodeDecodeError when I press the run button.When I run it with the command as_run from Command line it runs normally. Any ideas?
Nikos Barekas try to change the locale of your language to US (and restart). Salome has a problem with time and date when there are non Unicode symbols in it.
Nice video!. While selecting 3D: Automatic Hexahedralization, I am getting an error" Salome Exception : libquadmath.so.0: cannot open shared object file: No such file or directory". Why am i getting this?
libquadmath.so.0 is probably a debian dynamic library that you are missing. If you are running Salome-Meca on Linux Debian or Ubuntu, then you have to search which software you need to install to give you that library.
Hi Please explain elaborately. I tried but its not working Summary Output messages for stage Stage_1 Output messages for stage Stage_1 - [top / bottom] EXECUTION_CODE_ASTER_EXIT_7592=127 _EXIT_CODE = 127 back to top
I got the same error. probably, there is a library missing. go to the 'log'-file and search for "library" or "error" keywords. Like this, i figured out, that in my installation the "libopenblas" was missing. I could install that missing library in the ubuntu software centre. good luck!
Yes, you can do that. There is an option in the menu of Salome called “Dump file”. Do that and you will get a python script of all the commands used to build your model
I kept receiving this error even though I followed exactly your steps, I wonder if you have any idea how to fix it ? Run case "RunCase_1" calculations process started Starting "RunCase_1:Stage_1"... Stage "RunCase_1:Stage_1" start calculation (jobid=0) Copying result u'C:\\Users\\Tien\\Downloads\\CodeAster\\WORK\\Cuong\\plate2.resu.med' ERROR: Copy failed: [Errno 2] No such file or directory: u'C:/Users/Tien/Downloads/CodeAster/WORK/Cuong/Study1_Files\\RunCase_1\\Result-Stage_1\\plate2.resu.med' 1 result file(s) has(have) not been copied to their destination.

Are you using the windows install? Yesterday, I installed also this windows installation and after I tried I got the same error... I will get in touch with the developper of this windows install to ask (in the video I use the Linux install)
exactly, I just installed the windows version and got that error. It would be fine a "Green" pass, if I didn't set the output result. However, I checked the log file, there seems to be some errors (even though it displayed GREEN after the analysis). If you have some news regards this issue from the developers, could you please keep me posted as well ? many thanks
Cyprien, I've solved the issue, just by copying the whole folder of the program to C:\ I think the issue is somehow windows prevents the third party programs from writing to a file in some specific locations/folders. Just copy the Salome to a root folder or where you have admin access to it, it would be fine. At least mine worked !
Great idea thanks! Yesterday, the developer told me he had to check the problem, but it would be difficult because he cannot reproduce it... but if you solved it like that, that's great :)
Hi Cyprien, Thanks for the Great Tutorial!!

All three taking the same time ( 2 hours ) to finish the job, But i set a CPU processor and memory's are differently.
For System 1 : Memory = 4096 MB with 2 Processor
For System 2 : Memory = 3096 MB with 2 Processor
For System 3 : Memory = 4096 MB with 4 Processor
Any specification to set a Memory and Processor in aster ?
SYSTEM NO 1:
Memory : 7.7 GB
Processor : Intel Core i5-4460 CPU @ 3.20 GHz * 4
Graphics : NVD9
SYSTEM NO 2:
Memory : 7.7 GB
Processor : Intel Core i5-2320 CPU @ 3.00 GHz * 4
Graphics : Intel Sandybridge
SYSTEM NO 3:
Memory : 15.6 GB
Processor : Intel Core i7-7700 CPU @ 3.60 GHz * 8
Graphics : HD Graphics 630
How to make a run time lesser with higher configuration workstations.
Hi, please, somebody help me, I can´t complete any simulation because when I click run this message appears: "Cannot read output file or empty file.". I found some solutions but doesn't work for me
If you are on windows, try to install the latest version of Salome Meca.
Also try to remove any blank or space into the path or folder names where you project is saved.
Hi,
Do you know how to couple a OpenFoam and Calculix and Code aster ?
Using C++ and Python you should be able to do that... but you’ll need to develop your own API I think.. there’s nothing ready-out-of-the-box from my knowledge...
Thanks for the upload Cyprien. Very helpful video for beginners, as me!
Though, I can't run the analysis from Salome-Meca. I get a UnicodeDecodeError when I press the run button.When I run it with the command as_run from Command line it runs normally. Any ideas?
Nikos Barekas try to change the locale of your language to US (and restart). Salome has a problem with time and date when there are non Unicode symbols in it.
Nice video!.
While selecting 3D: Automatic Hexahedralization, I am getting an error" Salome Exception : libquadmath.so.0: cannot open shared object file: No such file or directory". Why am i getting this?
libquadmath.so.0 is probably a debian dynamic library that you are missing. If you are running Salome-Meca on Linux Debian or Ubuntu, then you have to search which software you need to install to give you that library.
Thanks for the reply.
what is the limit of mesh number
For any one else the "read mesh" option didn't apeared ?
Hi
Please explain elaborately. I tried but its not working
Summary
Output messages for stage Stage_1
Output messages for stage Stage_1 - [top / bottom]
EXECUTION_CODE_ASTER_EXIT_7592=127
_EXIT_CODE = 127
back to top
I got the same error. probably, there is a library missing. go to the 'log'-file and search for "library" or "error" keywords.
Like this, i figured out, that in my installation the "libopenblas" was missing. I could install that missing library in the ubuntu software centre.
good luck!
Thank you very much.
Can I save the entire project as a script in Python?
Did you make it?
Yes, you can do that. There is an option in the menu of Salome called “Dump file”. Do that and you will get a python script of all the commands used to build your model
good video for starting... thanks Cyprien
jdc.py error with the execution
What is this error ?
Thank you very good video for beginners
Thank you very much, Mr. Rusu!
may i know ur email? i have some question about this case. because there are some errors when I run it. thanks
Thank you very much for your videos.
Thanks for the Tutorial
I kept receiving this error even though I followed exactly your steps, I wonder if you have any idea how to fix it ?

Are you using the windows install? Yesterday, I installed also this windows installation and after I tried I got the same error... I will get in touch with the developper of this windows install to ask (in the video I use the Linux install)
exactly, I just installed the windows version and got that error. It would be fine a "Green" pass, if I didn't set the output result. However, I checked the log file, there seems to be some errors (even though it displayed GREEN after the analysis). If you have some news regards this issue from the developers, could you please keep me posted as well ? many thanks
Yes, sure, I will let you know. I want to solve this as well. I think it's probably a bug...
Cyprien, I've solved the issue, just by copying the whole folder of the program to C:\ I think the issue is somehow windows prevents the third party programs from writing to a file in some specific locations/folders. Just copy the Salome to a root folder or where you have admin access to it, it would be fine. At least mine worked !
Great idea thanks! Yesterday, the developer told me he had to check the problem, but it would be difficult because he cannot reproduce it... but if you solved it like that, that's great :)
Good video , good english
Nice video!
Thank you!
Hi Cyprien, Thanks for the Great Tutorial!!
I'm getting this #Execution_error while running a case
I've installed Salome-meca on my windows system, tried couple of your examples my self and also the inbulit testcases
I am getting this #Execution_error ruining any case as below, I'm a beginner in Salome-meca so can you please #help me figure out where the trouble is?
Error :- "SALOME.SALOME_Exception(details=SALOME.ExceptionStruct(type=BAD_PARAM, text='Cannot create directory C:\\Users\\****~1\\AppData\\Local\\Temp\\asterstudy_workdir_**\\****-ADITYA-OFFICE-Fri-04-221555.184/logs on host ****. Return status is 1', sourceFile='E:\\S-9.3.0\\MODULES\\SRC\\KERNEL_SRC\\src\\Launcher\\SALOME_Launcher.cxx', lineNumber=245))"
Looks like a problem of the Salome_meca 2019 windows version. Try to install the 2018 version. The windows version is not an official build and I heard that the latest version has some bugs
Hi@@Feaforall thanks for the reply, My useraccount contains space which probably was the problem, i created new username and tried running a test case ant It worked!!
Thank you so much
good exemple
