Detailed Description

Custom user supplied python scripts for material models. The python module should contain the functions

computeStress(oldStrain, oldStress, strain, state, time) # returns stress

computePK1Stress(oldF, oldP, F, state, time) # returns P

and optionally

computeStressTangent(strain, stress, state, time) # returns ds/de

computePK1StressTangent(F, P, state, time) # return dP/dF

else numerical derivatives are used. The state variable should be a dictionary storing either doubles or arrays of doubles.

This code is still experimental, and needs extensive testing.
