Hi everyone,

my question is a rooky one, simple and I am, admittedly, a bit ... well ... "shy" to ask.

I transformed a solid CAD file (in Space claim) into facets ... in order to add the internal lattice structure. I have problems meshing the whole thing in mechanical (Ansys workbench). The Patch Independent mesh takes forever ... and then reports failure - due to insufficient internal memory or simmilar.

I tried the following: - exporting the geometry out from space claim in STL format ... - then importing the stl file into the Inventor, ... - then exporting it again as step/igs/obj etc. and importing back into space claim/mechnanical.

The result is always the same ... :)

It is hard to say, but if you have many thousands of faces which are trying to be meshed, that might be a bit difficult for any mesher (of course depending on the size of the elements).

If you have/make a sample test iges file (not the real file), that gives you a hard time and that can not be meshed, feel free to post it so someone can have a look.

Also clarify what you mean with internal lattice structure. Is that just another way of saying interior mesh or volume mesh?
