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...

I came across oscillations in a pressure profile for a pipeline flow along the axis of a cylinder, how do I prove that these are not numerical err?

In terms of CFD, we often analyze the stability of the error using Von-Neumann analysis, especially for FDM based problems. Should we follow the same approach for a compressible fluid flow using FVM ?

What is the parameter that you are interested in?

If it is the stresses or the displacements in the pipe, then you can use contact element to model the soil-pipe interface.

Umberto Papa

you just try with Solidworks Solidflow Simuator. It's quite simple and so smart.
