[Gmsh] Duplicate Nodes in extruded mesh

[Zenker, Dr. Matthias]

Hi,

I had a quick look at your file (in gmsh). It seems like there is no volume, and the lines are duplicated. I would propose that you check and fix this in Solidworks. Also you could try to export in STEP instead of IGS. AFAIK gmsh digests the STEP format better than IGS.

HTH,

Matthias

Dr. Sabariego,

I'm writing as I found an old message from you regarding duplicate nodes in GMSH on a discussion forum.    I'm new to using GMSH and I was hoping that you could offer some advice on how to avoid this issue (after meshing, the duplicate nodes cause my FEA analysis to fall to pieces).   My methodology so far has been to create shapes in Solidworks via extrusion, then to import the .IGS file into GMSH and to mesh.  I've attached my .IGS file and my .MSH file in case you have time to look at them.  Thanks in advance for any counsel you can offer.
