Hi All
I have to export my solidworks model as STEP or STL models, to use in FEM analysis in another software, since I want to do 2D axissymetric analysis, it has to cut the geoemtries, and .... as a result, you know how the triangular mesh of the CAD model would be cut by a plane?? just arbitrarily? it might give very poor results, for that I should mesh geometry before importing in FEM analysis, so Solidworks gives me option to make a more dense mesh on STL model , BUT this mesh is for example for a cylinder, is very dense in the perimeter and very large in the height, I mean very long triangles that are set beside each other very tight
I wish it's clear in this photo
but I need it more dense that if you cut it with a plane it doesn't give a bad result
the FEM software has a poor feature for geometry mesh , before doing the FEM mesh , but I need a better one, any one has experience ?
