Hi again, I'm trying to use libmesh to replace some legacy custom FEM software. I need an output file where every line of text contains the value of a solution variable at the corresponding node in a VTK input mesh. For example, the value of the solution at node 5 in the VTK file should be at line 5 in the output file.
This seems trivial, but I can't figure out how to do this in parallel. MeshData doesn't work in parallel, and partitioning can introduce arbitrary reorderings of the Node ids. I can't figure out how to invert the partitioning so I can get the correct ordering for output. I looked a bit into the Xdr class, and it uses a space-filling curve to construct a canonical ordering. This isn't what I want-- I need the output node ordering to match my input mesh exactly so I can post-process the results with downstream software. ------------------------------------------------------------------------------ Introducing AppDynamics Lite, a free troubleshooting tool for Java/.NET Get 100% visibility into your production application - at no cost.
