Mesh error from .stp
Mesh error from .stpPosted by Leonardo Marcarini Borges at July 26. 2012
I am new to SALOME and I have been trying to do a linear analysis of the solid in the link below, but I can`t mesh this geometry and I don`t know why. Whenever I try to mesh I get this error: "GCPnts_UniformAbcissa failed"
The solid in question is a .stp import from a CAD model. I have tried to mesh it with many algorithms available, but the better results were given with the following algorithms (even though all of then gave me errors):
1D Wire discretization
2D Triangle (Mefisto)
3D Tetrahedron (Netgen)
I am using SALOME 6.3.0. 1D hypotheses was local length = 0.02, but I did try some others hypothesis.
Although I have been able to work around it by remaking the some parts of geometry (but not altering any dimension), I am most interested in what was causing the errors so in my future models I do not replicate them.
I had some others problems in the model before I could do some proper analysis (involving have to explode and fuse it in the salome), but that is for later . Thanks in advance.

"GCPnts_UniformAbcissa failed" appears when discretization of edges fails on edges with one vertex (instead of two), SALOME shows their length = 0.
To see these edges, select lines with "GCPnts_UniformAbcissa failed" in a dialog, click "Publish sub-shape", they appear in the Object Browser. As their length is close to zero, you can't see them in the viewer but you can explode them into vertices and see vertices.
