[Libmesh-users] xda/xta data formats

[Karen L. <kyl...@gm...>]

Dear libMesh users and developers,

I have successfully read in a mesh with data associated with the
nodes, and am trying to get libmesh to output it to a format that has
the new node ID's and the associated data values (because libmesh
renumbers all the nodes according to the order of appearance in the
list of elements). I need the data in terms of the new node values for
data processing purposes.

When I read in my mesh and mesh_data and then right away do
mesh_data.write("in_data.xta"), it only gives me the foreign id
(original) and the associated data values. When I do
mesh.write("in.xta"), however, I get the new node IDs (in order of
appearance in the elements in the original order). I have rather large
data files, and really need to process the output of a pde with the
original data... I haven't figured a way to do that via
write_nodal_data. Can someone help me out?

I tried to output the data in unv format, but just the foreign id with
the data values show up. I really need the new node ID's with the
data...

I'll really appreciate some help, thanks!
Karen
