Re: [ff3d-users] Convex sets

[Stephane Del Pino]

Dear Edouard,

you are right : it is not possible. There are 2 reasons for that.
- to use ff3d's fictitious domain technique, the characteristic function is 
mandatory,
- each triangle of the surface mesh *must* be inside *one* cell of the volume 
mesh.

One more thing. You may not know, since it is not written in the 
documentation, but you can use unstructured meshes to solve your PDEs. The 
unstructured meshes have to be read from files. The supported formats are :
- INRIA 'mesh' format
- gmsh format (http://www.geuz.org/gmsh/)

Regards,
Stéphane.
