I have a question. If you could help me, it would be very great. I have residual stress contour from "A" job. I want to extract the stress components from "A" job and use it as a initial stress state for "B" job. The main difference between "A" job and "B" job is "A" is pure mechanical, but "B" will be thermo-mechanical analysis. Is it possible to use "USDFLD" for that problem? Thanks!
How can I access cpress variable in usdfld? Or anything subroutine to be used for creating a user defined field output for calculating with cpress? Any help?
You have two option: 1- Using VUMAT and deleting element when they reach a certain criteria such as temperature or stress 2- Using USDFLD to reduce the material strength when they reach a certain temperature
Hi.. Thanks for the great video... I tried the problem exactly but the I'm getting the error "Problem during compilation" What could be the issue? My ABAQUS Verification shows "Pass" for all cases including "Abaqus/Standard with user subroutines" Could please let me know the versions of ABAQUS, Visual Studio and Intel Fortran Compiler (or any additional softwares) that you are using or which will run successfully...
Hi, This error is not the only for linking problem perhaps you have an error in your subroutine command. I would recommend you check your linking status by running one of my products on the website to check if it works then you can go for further steps. hyperlyceum.com/product/an-example-for-dflux/ Please ask your further question from our website.
Hi. I also had the problem during compilation messages after submitting job and A UMAT file. I solved it by testing a much simpler subroutine DLOAD, and USING THE WINDOWS POWER SHELL to run the analysis. Power shell somewhat show the errors in the code and after correcting code/syntax, the subroutine ran perfectly. Did the same for UMAT subroutine, debugged the code, checked the error messages to see what was missing and added the missing stuff. The job ran perfectly inside ABAQUS. You can find videos on DLOAD and UMAT codes on youtube. Just need a bit of patience to debug problems.
I have a question: I WANT TO CHANGE DENSITY AS A FUNCTION OF TEMPERATURE VALUE AT EACH INCREMENT, HOW TO CALL IT IN USDFLD SUBROUTINE?? PLEASE HELP. I mean , how to update density variable as function of TEMP solution value?
Hi, You don't need USDFLD subroutine for this task. You just need to activate temperature dependent box in density panel and insert your temperature dependent density in the table. You can use this link: 130.149.89.49:2080/v6.11/books/usi/default.htm?startat=pt03ch12s08s01.html Follow the 3rd step.
Dear sir hello and for the useful video I got the following error: ERROR IN JOB-USFLDBEam: Problem during compilation - C:\Users\ASUS_PC\Desktop\USFLD_Beam.for What should I DO to resolve it Thanks
Sir, what does the "Field(Y)/0.01" mean? Also, what does sdv show here?

Dear sir, Can you suggest to me a reference or a video to do the residual stress subroutine SIGIN for a model.
Thanks in advance

hello sir do you solve the problem where property varing along 2 direction say r and theta in heat tansfer problems?
i have made a dflux model but i am not able to delete element and make cavity on the surface. what should i do?
You have two option:
1- Using VUMAT and deleting element when they reach a certain criteria such as temperature or stress
2- Using USDFLD to reduce the material strength when they reach a certain temperature
CAN WE USE THIS TO DELETE ELEMENTS BASED ON TEMPERATURE?
Is it possible to do the same in the initial step?
very well explained
Thank you
Hallow Sir can you provide internal heat generation (constant) for HETVAL subroutine in FGM materials (cylinder).

@Bold Learning I am also facing same issue"Problem during compilation".How did you resolve it??
plz tell

Can we use USDFLD for stress-strain-temperature relationship?
Hi,
AS long as you can define field variable you can use usdfld.
So yes you can
@@hyperlyceum60 Thanks for the reply.
I'll try to do it. 😊
Excelent video!Thank you very much Sr. Would you please explain how to use the CREEP subroutine in Abaqus?!
Hi,
We will let our tutor know about it,
Hopefully, he can make it soon.
in PowerShell it says The .inp extension has been removed from the job identifier

Search how to link Abaqus to Fortran compliers. Dr. Ronald channel you will find the video.
@@mera_baba_ ok thank you
@@mera_baba_ but I don't think that the subroutine USDFLD need to link Fortran compiler with abaqus
@@bensaidismail5394 it is sir please do it.
@@mera_baba_ thanks
Dear Sir,
Can you help me in my project. I am using usdfld suborutine.How can I contact you?
my text file is not converting into .for file.... please help
HI,
Please check the extension box under the view tab on your window then you should be able to do it
@@hyperlyceum60 thanks
The access to the file is forbidden. Just "bought" it for 0$ but its denying the access to it.
try it now
It should work now
@@hyperlyceum60 not working for me too...
HELP ME SIR
