Dear libMesh team,
In my application, I write the results to two files using:
mesh.write("mesh.xdr");
systems.write("systems.xdr",libMeshEnums::WRITE,EquationSystems::WRITE_DATA|EquationSystems::WRITE_ADDITIONAL_DATA);
Then, in a different program, I read in these results using:
Mesh mesh(3);
mesh.read("mesh.xdr",NULL,true);
EquationSystems systems(mesh);
systems.read("systems.xdr",libMeshEnums::READ,EquationSystems::READ_DATA|EquationSystems::READ_ADDITIONAL_DATA|EquationSystems::READ_HEADER);
This used to work well. However, I now updated to the svn head
version (before that, I had a version that was several months old).
When I now read in results that have been written with the old
version, I get completely wrong results. If I re-run the simulation
and then read in the result, everything is fine again. Hence, I
assume that there has been a format change in the xdr files; can this
be? If yes, is there any way to read in files that have been written
in the old format? That would be very useful for me since otherwise I
would have to repeat quite a lot of simulations.
Note that the change seems to be in the "systems.xdr" file, not in the
"mesh.xdr" since loading an old "mesh.xdr" together with a new
"system.xdr" works well.
Also note that the simulation that writes the results runs in parallel
(number of processors > 1), whereas the program that reads the results
runs on one processor only.
Any help is appreciated.
Best Regards,
Tim
