Hi.
I would like to model quasi-static compression of foam made of Al2O3. I tried with explicit but due to very small element size (0.2) and amount of elements - computation time is very long. I would like to try implicit.
First I would like to create a working model for a low elements and simple component.
Below are the data for Al2O3 taken from the Radioss manual for /law/mat79.
For compression test I need failure.
In the manual :
https://help.altair.com/hwsolvers/rad/topics/solvers/rad/mat_law79_john_holm_starter_r.htm#mat_law79_john_holm_starter_r__mat_law79_john_holm_starter_r_fn_zrj_t4h_vz
there is 'Idel' option mentioned. But I can not see it in my settings.
So what can I do with failure ? There is also no /FAIL/MAXSTRAIN availabe which seems to be best and simple for this material

Any hints about the best aproach are welcome 
Model attached.
