thanks!
Hello, very informative. Thank you so much. What happened to the Allclean tutorial part? There is only Allrun in the actual footage
This tutorial is not exactly correct. relativeSizes parameter does not define what set of parameters will define layes (first layer, final layer thickness as well as expansion ratio can be set independently). It defines whethet or not the measures are taken relative to the size of adjacent cell or in absolute values (meters). The second mistake is that the size of the layers are not computed by dividing on the factors, but multiplying with them: the final layer will not be as twice as small as the adjcent cell, but actually two times bigger!
What should be the name while using the invert command if multiple zones are already defined with different names, and I want to invert the last third zone?
Respected Sir, I want to use pisoFoam and laplacianFoam for fluid and solid region respectively. Can you please suggest the possible ways?
Hi, nice video, thank you. I have a question, can we add cells outside of blockMesh using toposet ? Or it must be inside blockMesh ?
how to use topoSet for multiple STL files?
For anyone concerned, this is what you do if in OpenFoam v10 you cant find the polymesh in constant. It is normal. Just do what the guy does. Well done mate , thank you so much!
hai, i am started to learn the openFOAM, I am following your videos and getting error while giving blockMesh command (Symbol Lockup error : libdecompositionmethods.so : undefined symbol :ZNK4Foam11regI0ObjectENS_.......like this). please solve my problem
Thank you!
thank you so much.

Thanks for video. Is it really fast to complete simulation in openfoam compared to ansys? It took me 5 hours to complete steady state simulation of 8 milllion elements. So, will this simulation run faster in openfoam?
I have a problem putting the geometry in the Mesh with paraFoam.could you please tell me how to put it right in the Background Mesh
one the best videos that i saw. I would like to know how can trace or execute Particles ( as Particle Tracking ) in this box ! i ll be glad to know that .
Seriously I saw lot of videos... But it was the most simple and best one for beginners... Thanks a lot and please make a video from scrap to pro if possible.. like a series of lectures...
This is really good tutorial example for multiregion mesh model coupled with Third-party meshing program like Fluent.
Hello, I want to use your method to divide a blockmesh into two unconnected computing domains, such as deleting the water in your video. Can such an operation be achieved?
Je t'aime ❤️
thanks a lot. can u please please please please make a playlist on rheotool tutorials ?
where is the next one??

Boundary Conditions and controlDict setup...can you provide
This was informative but you have not discussed action clear and delete; I am trying to understand the difference between actions clear and delete? I shall be grateful for guidance
can you run a tutorial on snappy hex Mesh with relative sizes false; (for layer size). Please!
Hi. I am using snappyHex to create mesh out of my stl surfaces. How can i keep the all bodies (you know snappy removes)? I tried as Tobias showed but still removes the bodies. Thanks.
I'm wondering if you have an example of how to set up an axisymmetrical case of chtMultiRegionFoam? I want to try to simulate the cool-down time of an insulated pipe in water. The insulation is a little complex, so it's not just a simple 'layer thickness'. I am able to share with you what I have done, but I am having lots of trouble getting the dictionaries set-up and perhaps the 'changeDictDict' approach is actually what I need to assist.
Hello, thanks for the video I have a conjugate heat transfer problem, few electronic components being cooled directly by a fluid (immersion method of cooling) and i am using OpenFoam for this. I am using toposet to identify different solid components inside the background mesh. Since some of the components are very thin (like a solder layer 0.1mm thick), i have to use a blockmesh with very high number of elements in each of the three axis. If the background mesh is not fine enough, toposet is unable to extract these thin solid components. I have to play with the backgroud blockmesh so as the toposet identifies all the solid cellZones successfully. Of course i can use snappy, but i do not think so i can get the same quality hexa mesh as given by blockMesh. Any idea how to make sure that toposet identifies a particular cellZone successfully without using hit and trial with background blockMesh? thanks
Great video, is it possible for the CellZones identified by toposet to be refined etc means enhance the meshing of that particular cellZone ? thanks
There is a suggestion, the '&' should not be put at the end of each line because that means all the commands are running almost simultaneously. for some complicated simulation, even the blockMesh would take several minutes so the second step would not wait for it finishing.
I have seen some Allrun files. Although I can roughly know the meaning of each line but I don't know how to do it. Your video makes it easier to understand! Please keep updating!
In the download link the streamlines file under system is probably missing.
How to add a constant heat source in watt ?
hi foamdude, thanks for wonderful explanation. Not sure where the solidmodel is, how to give BCs on that solidmodel?
Its a nice video and very helpful. Thanks for this. Could you please also explain how the bounding box dimensions are given? I don't understand only 2 points given in the box but the box has more number of points!!.
Thanks for the nice tutorial! Is it possible to start the simulation as well? I tried to start the simulation with simpleFoam, but didn't get a result. .
Thanks a lot!!!
Aerodynamics of a cow tutorial?
Amazing video, i understand the way of creating the cell zones, but what is not clear for me is how to determine the boxes. Could you please help me in this? thanks!
to specify the box, you provide min and max values for x y and z. The openfoam wiki has a general formula, and the multifoam dam break case has a good example. If you'd like to see it in action, you can look at Joszef Nagy's multifoam tutorial Part One. Good luck!
He also has an example here with "box (xmin ymin zmin) (xmax ymax zmax)".
@@EnigmaticIguana thank you! It worked.
@@markcsete1570 Glad to hear it!
Thank you very much! Very clearly explained for non-experts.
Tank you, really good Video! Does soneone know why all my cells are divided into triangles? In your case its only cells close to refinement...
good video!
I have no SnapyHexMesh file in my pitzDaily's system folder, why? .... I'm using OF v7 in ubuntu
You have to copy that file and also meshQualityDict. Those files are in $FOAM_ETC and then in templates/inflowOutflow/system/ In this video he says it in 4:55
@@TheAurora1993 thanks for reply, I have another question, I have a 2D model (from Blender) and want to set this mesh for OF, where I must declare one cell in the z-axis direction?. This tutorial and lots of them are for 3D mesh but I couldn't find for 2D mesh
@@jaa70 Okay, I'm just learning about OpenFoam, but I have learned that OF only works with 3D objects, and if you want to mesh a 2D object I think you have to declare surfaces as "empty" in blockMesh or something like this. I think the best thing you can do it's open the object in paraView and see the axis. You probably have X and Y, so yes, the Z-axis direction should have 1 cell thickness. ¡Buena suerte!
@@TheAurora1993 thanks , I will try it.
@@TheAurora1993 hey! I was finally able to do it: th-cam.com/video/g1u5GuDlyr0/w-d-xo.html
Hello sir, I have a circular fin heat exchange case. Which solver should I used.
Could you please give me your contact number. I really need some help.
when I run snappyHexMesh it gives me this error :( cannot find trisurfacemesh starting from...................
dude, how to customize the layout of OpenFOAM
Very nice! For a long time i been looking for a clear simple explanation of these tools, im glad i found your video.
i use ubuntu so how do i copy my stl file in the trisurface directory
just with your file browser, it is the same as in windows
4:27 Hey man. Thank you for the video. How did you add the axes in the background in Paraview?
Nevermind, got it. "Axes grid" in properties.
