Mesh Control

Mesh controls define the characteristics of a mesh. Mesh controls specify the minimum or maximum size of the elements, the distribution of nodes along edges, hard points and hard curves, mesh ID numbering, mesh ID offsets, and the displacement coordinate system. The functions described in this section provide access to the data and contents of the Creo Simulate mesh control objects. Mesh controls use the ProType field in the ProMechitem structure as PRO_SIMULATION_MESH_CNTRL.
