MAPDL compatibility

Note

Placeholder. A deep dive on the MAPDL-interop surface lives here: CDB / RST / EMAT / FULL / MODE / DB read + write matrices, KEYOPT option parity per element, and the mapping from MAPDL commands (ET, MP, R, D, F) to Model methods.

Landing in the next documentation pass.

For the current at-a-glance status of the interop layer, see MAPDL interop.
