I am trying to simulate a triaxial test on a soil specimen. But as soon as we apply the confining pressure, the top and bottom plates vanish. I have attached the data file. Please suggest the required corrections. It would be very helpful.
Thank you for the reply. I looked into the material modeling files. I tried to understand and run the triaxial model, but the issue still exists. Also, I am not familiar with the fish language. Could you help me understand if there is any error in the code? I have shared the data file in the previous question, if you could take a look at it, it would be of great help.
