Thank you for your reply. What i meant is that I already defined my soil with Cam-Clay and i prescribed initial stress state conditions and gravity to my soil but i am running the simulation and it is failing.
Can i know what type of 3d element to use for cam clay and what are the steps to follow to have a successful simulation? (Note that I am using ANSYS workbench 2020 R2 with full educational license)
Your help is deeply appreciated. Thank you in advance
