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. _______________________________________________ ff3d-users mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/ff3d-users
