To use separate refinement patterns. For a simple example, the solute layers you might want to adaptively resolve in a concentration variable for a transport problem won't necessarily have anything to do with the boundary layers and/or corner singularities in the velocity/pressure variables. It's not a bad idea, it's just very hard to do in such a way that the computational overhead of maintaining and integrating on separate meshes doesn't overwhelm the computational benefit of getting the same solution quality with fewer redundant degrees of freedom. --- Roy ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
