Compatible Products: – | Pro | Premium | Enterprise | Ent PP | Ent Solver | DYNA


Key indicating the type of meshing to be used:



Use free meshing (the default).



Use mapped meshing.



Use mapped meshing if possible; otherwise, use free meshing. If you specify MSHKEY,2, SmartSizing will be inactive even while free meshing non-map-meshable areas.

Command Default

As stated above, free meshing is the default. However, since the MSHKEY and MSHAPE settings are closely related, you should refer to the table in the MSHAPE command description for more information about defaults.


The MSHKEY, MSHAPE, and MSHMID commands replace the functionality that was provided by the ESHAPE command in ANSYS 5.3 and earlier releases.

This command is also valid for rezoning.
