I was doing a coupling procedure with oofem and used the liboofem. I simulated the rubber with the hyperelastic material.
As following:
####
import liboofem
mat = liboofem.material("HyperMat",1,domain, d=1100, K=1.0e7,G=3.03e6)
domain.setMaterial(1,mat)
####
As result, it showed the error like that:
Error:(/oofem/source/bindings/python/oofemlib.cpp:1620)
In material:
material: wrong input data

Anyone could tell me how to deal with this problem?

Best regards,
