Hi all, May I ask whether in WB 2022 R2 the Nonlinear mesh adaptivity supports anisotropic material defined by command snippet?

I read the ANSYS help that only the following materials are not supported for Nonlinear adaptive remeshing. When I run a model, the program was terminated with an error message stating that:

Element 455645, which is part of the new mesh generated during rezoning, is associated with material 98, which has material defined  by TB, ANIS, with material table number 1 and type 5.  This material      is not supported by rezoning.  Checking discontinues. 

Could anyone give a hint on this?

Thank you in advance!

Hi,

The error message indicates that the Nonlinear Mesh Adaptivity (NLAD) feature is not compatible with anisotropic materials. Ansys Help for 2022 R2 version discusses some materials that are not compatible with NLAD; however, you can refer the most recent documentation for more details on material models that are compatible with NLAD - 2.3. Nonlinear Mesh Adaptivity Requirements and Limitations

Hope this helps!
