Hello, I have a question concerning the way how physical entities are exported. I would like to use the concept of physical entities to handle boundary conditions. From the documentation and my experiments it seems to me, that on output the mesh contains the elements associated to individual physical entities. My problem is following: if the physical entity is some part of boundary (curve in 2D or surface in 3D) of the whole domain, I need in some cases somehow to relate this information to domain elements, not to the "elements" discretized on the boundary. In the case of square 2D domain, where boundary condition is applied to one side, I need to pass this information to 2D elements, that have heir edge on this side. 1) Is there some way how to get this information from mesher? 2) If not, one can reconstruct this information from a list of edge-elements generated for this side. Does such a tool already exists?
Thank you Bob _______________________________________________ gmsh mailing list [email protected] http://www.geuz.org/mailman/listinfo/gmsh
