I would like to ask, How to model material properties as elastic tensor instead of using Young modulus and adding material properties models after that. To clerify the question, is it possible to enter mechanical properties in a similar way to MAT2 card in Nastran. Best Regards

If you set Solid Model in Linear Elastic Material to Anisotropic, you enter the elements of the elaticity matrix directly.

In the Shell interface, there is also a similar material model called Section Stiffness, where the full stiffness matrix of a shell is given explicitly.
