  • Extra element structures added during meshing

    Posted by John Smith at March 23. 2008
    Hi,
    Ive been using CAELinux/pclinuxos/salome 3.2.6 version (smesh), and I get a meshing error and the model picture shows "cancerous growths" of mesh regions that extend beyond normal part boundaries.  Any suggestions about the potential cause?  I have a screen shot to look at if there is a way to attach to a message - though basically its a rising random blob of mesh elements sticking above a flat plane.  Different parts I have run have this "growth" in various areas (and sometimes a part meshes ok).  CAD models are imported step files from Catia V4/V5, using mesh algorithms Tet(netgen)/Triangle(mefisto)/Wire discretisation/segments around vertex.

      The error I get when Mesh computation fails is "Tetrahedronn (Netgen) ... Exception in Ng GenerateVolumeMesh()".
