One more question: ok, now I have the solution at the nodes. I read in other posts that to evaluate the results in any (x,y) I must get the shape functions of the element at (x,y), multiply by the coefficients and accumulate. This is no big deal, but ... is there any function in libmesh to help me with that?
The overload System::point_value(var_num, point, elem) is the simplest function to use when you're evaluating the system's solution on a local or algebraically ghosted element, but you're evaluating a custom serialized vector, and we don't have any helper functions for that. You'll be stuck practically copying and pasting the code that's in that point_value version, I think. --- Roy ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
