Hello Ansys Community,<\/p>\n

 <\/p>\n

I am trying to simulate an unconsolidated undrained triaxial compression test through static structural analysis, however, the software keeps on telling me that it doesn’t converge to a solution. My goal is to create a similar stress-strain curve in the software with the experimental results that I have. What I did is that I created a Soft Clay material with a Mohr-Coulomb model and after that, I created the cylinder model under triaxial compression but I am not sure if I used enough boundary conditions. I would also like to add that this is nonlinear. <\/p>\n

The following screenshot is what happens and I can’t seem to move forward from this.<\/p>\n

I am not sure what data I should show but if anyone can help I am willing to give what is needed for your understanding. <\/p>\n","protected":false},"template":"","class_list":["post-278585","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
