suppose if I have a function as below
f=exp(S11-s22).
how can I get a contour plot of above function in abaqus visualization module.
s11,s22 are stress values of the same step(same frame also) in an analysis
Hi Narayana
however ur question is not so clear, but if you mean u wanna get for example an element in S11 and S22 condition, thus, u can go to the ODB field out put and select the wanted elements by choosing once S11 and then S22.
then, go to "Operate on XY data and easily deduct the values from each other.
If I didnt ur question well, let me know to help u in case.
Click Tools>Create Field output>From fields and then define your expression. The new field variable will appear in a new ""Session step" in output base tree.
Just a complement to Ashish Kumar Singh. You can also create a UVARM subroutine which can then be plotted with Abaqus CAE.
I do not agree, Niraj Kumar Jha. To me, the use of the UVARM subroutine corresponds exactly to what is asked (creation of a new field based on the standard field output stored in the odb file), not the USDFLD, but I may be wrong. Can you give more details on what you have in mind?
Dear Khaled Ghaedi.
Thanks for your reply. As you said I can only create XY plot of required function and time step.But I want to create the contour plot of the function for all elements like von mises stress contour plot which will be created automatically in abaqus visualisation module.
1) I agree with Vincent, the subroutine UVARM solves the problem.
2) The suggestion by Ashish Kumar Singh works well for one particular increment. However, if multiple increments are needed, this could be a little boring.
Dear Ashish Kumar Singh
Thank for your reply.I was able to create field output by operating on the stress field of different fields and different frames e.g s2f2_S + s3f2_S.But I want to create plot for expression given below
s2f2_S_S11+ s3f2_S_S22
when i tried to this, abaqus is saying s2f2_S_S11 is not defined.
can you please help me solving this?
Dear Vincent
Thank you very much for your help. I was able to create a contour plot of the function using UVARM subroutine.
Can you please provide a script with this subroutine? I need to do post processing of something similar to f=exp(S11-s22).
