Geometry fails to explode properly was created by Andy Foan
On larger models which I'm partitioning to enable me to solve with two different materials the explode fails to work properly. I explode the model to two solids then each solid to its faces. Exploding Solid 1 numbers its faces from 1 to n, then sometimes (on models with 300 or more faces) exploding Solid 2 numbers its faces from 1 again. Then when it gets to the Aster Load Case Wizard it produces the message "Name ambiguity between the selected shape and some of its sub-shape (same name)".
Do you know why this is and how I can stop it happening?

Dear Andy,
this is probably a "design" problem of the Salome-Meca platform, but there is a more efficient way to do what you want: define groups!!
Instead of extracting each face separately, just use the "create group" command in GEOM, and select each group of face that you will need in the FE model (drawing a small sketch of the FE problem will help you much in this task). For a generic 3D study, the groups that you will need to create are:
1) group of faces / edges / vertices to apply boundary conditions
2) group of volumes to define the material assignement
3) eventually other groups for post-processing purpose
According to the developers at EDF, the use of groups is the "recommended" way to work in Salome-Meca.
I hope that it will help you.
PS: if you directly explode all the faces of your "Compound" you will get a continuous numbering of the faces...
