DataPostprocessor for two DoFHandler s

[Anton]

Hello,

I would like to compute a scalar field for outputting purposes.  The field is a result of postprocessing of two solution vectors belonging to two different DoFHandler s, but living on the same Triangulation.  Is there functionality for doing something like this in the library, or does one have to combine the two vectors into one by creating an FESystem with an associated DoFHandler first?

Sincerely,

/Anton

If you want to send results through a DataPostprocessor object, you'll
have to combine the data first (because a DataPostprocessor only gets to
see the values *of a single solution vector* at a time). Either step-31
or step-32 has code that shows how to combine things into a single
DoFHandler.

Best
W.
