Hello,
I want to simulate the triaxial compression test of rock.I use the JCFpmMat to simulate rock.(I refer to the uniaxial compression test of [1] and the example script-session1.py[2]) 
My question is as follows(maybe stupid..):

1.The purpose of Isotropic compression stage is to make the particles dense,right?If so,in my script I use the randomDensePack,Is it necessary to retain this stage?

2.In the deviatoric stage,the example use triax.goal2=rate to control the compression.I also try to use it in my script(triaxial with JCFpm),but after 4500000 iter,I can not get the ideal total stress-strain curve.(Is it related to my material parameters and strain rate?)

3.With the JCFpmMat,I can record the number of ShearCracks and TensCracks.Can you give me a suggestion on how to control the end of the test (specimen compression failure)?

Best regards.
