desire to not mesh using datum points

desire to not mesh using datum points

desire to not mesh using datum points

(OP)
I've recently noticed that Mechanica will mesh using any datum points in the model.   As I am analyzing a fan blade with 4500 datum points (for profile curves) and I really don't want the mesh to be that fine, how do I tell Mechanica to not mesh using datum points?

The work-around I currently use is to pattern the blade and then cut away the original.  I cut away 3/4 of the fan disk anyway to use symmetry in Mechanica so that step is no big deal.  I just think there should be a more direct way of telling Mechanica not to mesh to datum points.

RE: desire to not mesh using datum points

Jim,

I thought there was a setting to do this in an AUTOGEM control, but this is not the case.  It certainly seems like an "easy" option for PTC to implement/provide for those who need it.

The only other ideas I came up with were basically workarounds, similar to what you are already doing.

Sorry that I couldn't be more help today.

Peter
