Hello, I am simulating soil and pile using Sanisand on Abaqus.
I have problems with the analysis because of the value of the parameter 18. When I use small values, The analysis fails, and when I use large values, it gives wrong results.
Please help me.

Dear Norma,
those are sanisand parameters used for karlsruhe sand, i faced the same problem, i changed the parameter number 18 many times in order to get very close stress strain curves for triaxial test with hypoplastic sand model.
