Dear developers, I want to get the hessian on a mesh point. I find that there is a function point_hessian in fem_context.C. How can I get a FEMContext object? I don't have "context" in my code. FEMContext &c = libmesh_cast_ref<FEMContext&>(context);
Another question: Is the output file (for example, tecplot) for solutions obtained using 2nd order type elements more accurate than that using 1st order type elements? Are those values of mid-points on sides used to display the solution in tecplot? Otherwise, it would be too course to show the result. Thanks. -- Li Luo ------------------------------------------------------------------------------ _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
