[Dune] initializing parallel user data from file

[Dedner, Andreas]

Do you have the grid and data vector on one process and want to call
loadBalance on the grid?
If thats what you need, you can use the loadBalance method taking a data handler.
An example is given in the lloadBalance method on the GridPtr class
dune/grid/io/file/dgfparser/gridptr.hh
If you need something different then ypu need to provide more information...
Best
Andreas

Subject: [Dune] initializing parallel user data from file

Good morning duners,
I would like to initialize a parallel user data vector from a grid input
file.
The grid files (.vrt and .cel) are in PROStar format and the last column
of the .cel file contains the values of the scalar field I want to use
in order to initialize the user data vector.
Is there a standard way to do this?
I tried some ways but I always need to communicate a global id. Can I
avoid this?
Thank you for your help.

Marco
