Yes and no. The hierarchic FE type (on at least some geometric element types) can in theory be p-refined (or adaptively p-refined) to an arbitrary p... but with the current implementation, you're not going to get very far (less than p=10 in 3D, IIRC) before your solutions are swamped by floating point error (either from the shape function evaluations or the system ill-conditioning, I can't say which). Your suggestions for improvement would be appreciated; I couldn't say how much work would be required without some better idea of what the work would entail. Implementing more FPU-stable shape evaluation functions might be easy (albeit tedious). --- Roy ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Libmesh-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/libmesh-users
