Hello Fritz,

I found the following from our knowledge database:

"In general, SPG is compatible with all solid material models that use Cauchy strain for stress calculation. Ortho-/aniso-tropic material laws (including those using deformation gradient for stress calculation) need special treatment, so they are generally not supported."

Which anisotropic material model are you thinking of using?

Note that we are planning to add the list of material models supported by SPG in the LS-DYNA user Manual Vol II at some point in the future. I will contact the developer to get you a list now.

 

Reno.
