Can the elastic matrix be modified by oneself in Solid Mechanics model?

Hi

We all know that elastic module E and Possion's ratio mu are needed in Solid Mechanics model. Then, the elastic matrix is assembled according to both of them. however, a NEW elastic matrix can be assembled by oneself ? In other words, different domains own different constitutive relations in a model.

Thanks a lot!

Hi,

If you change the Linear Elastic material model from Isotropic to Anisotropic, the input is the elements of a general elastic constitutive matrix.
