Hi Moustafa Sorry, I just pasted my code which actually contains things you can't know, like df and cl (which are aliases of other modules I wrote). I first reply your questions in the right order: 1) No, this is part of the script I use to create the model. Of course, however, I firstly...

Hi Moustafa. Here my code (it should be self explaining): [...] # Keywords without nodes/elements m.keywordBlock.synchVersions(storeNodesAndElements=False) # Get position of *INITIAL blocks init_blocks = [block for block in m.keywordBlock.sieBlocks if ('*INITIAL' in block or '*Initial' in...

Hi Moustafa. Sorry I never posted my final solution. I intended to do it, but never had time in the last months... In any case, I solved the problem by initializing the field value for each node in my pressure dependent material with python. To do this, I had to add them to the keywordBlock...

Thanks for the reply. I discovered that *INITIAL CONDITION with odb is only possible for . I also had approximately your ideas. Today I tried to implement the first one: I added a step after my geostatic step and i controlled via subroutine the increment time, so that the change in field...

Hi Bartosz! Thank you for your reply! Yes, the field variable is the volumetric stress and since I know the initial stress distribution I could calculate the values for each point using its coordinates. The problem is that I don't know how to initialize a field variable which is different for...

Hi, I'm trying to model a stress dependency of the Young's modulus of an elasto-plastic soil (Mohr-Coulomb) in Abaqus using the subroutine USDFLD (in plane strain conditions with CPE4 mesh elements). My first simple implementation is: SUBROUTINE...
