We are working on Midplane for our analysis and looking at advantage of 3D mesh.Kindly let me know your comments +ve/-ve...
Thanks in advance for your time.
If part wall thickness is on higher side you can always opt for 3D mesh, but your analysis time will increase here. You can use 3D mesh when part is complex, thickness of wall is high, some extra features etc.
Midplane gives you freedom when part is simple, not much features, & time is very short.
