problem of contact in LMGC90 due to gmsh
Hello,
I am doing some seismic dynamic simulations with the software LMGC90, based on python.
The models are composed by several blocks that are in contact between them.
The input of this software is a mesh file, done with gmsh, starting from a stp file (from catia).
For some configurations/models, LMGC90 does not read the contact between the blocks. The step file and the python script are OK, since for some configurations everything is fine. So I guess that the problem comes from the mesh done with gmsh. I have tried to reduce the size of the mesh, but in some cases it doesn't work.
Do you have an idea how to solve this problem? many thanks in advance regards luca
