BoundedCamClay

[lisandroroldan]

Hi, I'm trying to use the BoundingCamClay model.
The script I wrote runs fine with ElasticIsotropic and J2Plasticity materials, but when I use a BoundingCamClay model OpenSees.exe stops working! It doesn't even give me an error...what could be the reason? I attach the scrip:
