Is it possible to export both the linear and non-linear material properties to file, for use in a different Ansys model? The MPWRITE command documentation states that it only writes the linear properties.


Yes. If you use the "LIB" option on the MPWRITE command, both the linear and non-linear properties are written to the file in the "MATERIAL LIBRARY" format. e.g. MPWRITE,<file>,<ext>,, LIB, 1

See example output file below:
