How can I disperse Al2O3 powder in molten Al A356 in compo-casting method?

Al2O3 particles don't have wettability with molten Al. They float on the surface of the molten without any change in structure of particles.

How to define an anisotropic material with asymmetric elastic compliance/stiffness matrix in ANSYS APDL?

I need to model an anisotropic material in which the Poisson's ratio ν_12 ≠ ν_21 and so on. Therefore, the elastic compliance matrix wouldn't be a symmetric one. In ANSYS APDL, for TB,ANEL...
