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 :class:`~femorph_solver.Model` methods. Landing in the next documentation pass. For the current at-a-glance status of the interop layer, see :doc:`/getting-started/mapdl-interop`.
