I'm trying to mesh a 3D mold block for a FEM Cool analysis. The surface mesh looks fine, but when I go to create a 3D mesh, i get the error that meshing has failed due to surface defects. The mesh log says there are 6 non-manifold edges, but I cannot locate any of them using the various diagnostic tools. Free edges text diagnostic says 0 free or non-manifold edges and none are highlighted when I use the mesh display. I also looked at element orientation and at intersections, but I cannot find anything wrong (other than the aspect ratio you see here)
What do I need to do to mesh this mold block? It's a very complex multicavity inserted job with over 4 million part elements, so I don't want to start over from nothing if I can avoid it.
Please see attached image for more information.
Solved! Go to Solution.
I never meshed a mold in 3D.
But I think your trouble don't comes from the manifold edges.
I believe Moldflow cannot mesh a part when the maximum ratio is superior to 50.
So try to correct that.
Once in a blue moon, I do encounter unexplainable errors when trying to mesh 3D from Dual Domain mesh. One great tip I received from Autodesk support is to export the DD model to patran format > import back > mesh 3D. Works every time. You may want to try that.
