An error - too many attempts made for this increment

[taitameage]

Hi,

As I mentioned before, I have a quarter model in Aaqus 6.12 which stands for an entire model of a rectangular plate with a centered hole. I used the orthotropic anisotropic material and defined those 11 constants (c, D, b1111, b2222, b.......). When I did biaxial stretching, I got an error which said

"Too many attempts made for this increment."

I have tried
- to increase the number of iterations per step,
- to adjust loads,
- to change the element size,
- to add automatic stabilization,
but they do not work at all.

I appreciate your help in advance.

did you try *analysis = discontinuous it might help
