MSC.GS-Mesher / SurfaceMSC.GS-Mesher / Surface
Accuracy of Mesh Depends Strongly on Geometry
Sliver surfaces, small details (e.g. holes), will result in too many and/or bad shaped elements.
It is not always possible to create high quality elements (e.g. surfaces have bad parameterization)
If Geometry is non-congruent, Mesh will in general be non-congruent too.

Accessing this “piston” took 30 seconds. (It took 5 minutes to import it into MSC.Patran 2000 r2 )
No Cleanup needed. Piston appears as Solid and can directly be meshed.
Mesh can be Controlled:Several “Mesh Properties” can be Created and Assigned to Parts of the Model.
