Creating a rounded Mohr Coulomb nDMaterial in Openseespy  #142

Dear Dr. Zhu,

I am building a 3D finite element model for geotechnical engineering, using standard brick elements to model the soil.
I am wondering if it's possible to create a rounded Mohr Coulomb nDmaterial in Openseespy?

It looks like this can be done using the Template3Dep nDMaterial in the Tcl version to achieve this:

But I couldn't find the equivalent in Openseespy.

If this is not available in OpenseesPy, how would you suggest building a rounded MC material for standard brick element?

Thank you,
Weikuang Lei
