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...

It could be simulated effects of vegetation hydrodynamics modelling by roughness coefficient. For ex. Delft3d is good model to do that.

EFDC(Environmental Fluid Dynamic Code) provides a module that allowing users to input different kinds of vegetations in order to creat a vegetation map in your computational area. Parameters of vegetation are like plant density, stem diameter, stem height, etc.
