I am currently working in the development of a CFD code which outputs pvtu files with cell mesh and field data. However, every of this pvtu/vtu files holds the complete mesh and field data. As in most of the simulations the mesh data does not vary, we were wondering if anyone has been able to split mesh and field data in pvtu files. This should allow to reduce substantially the storage sizes to save important data of unsteady simulations. Of course if the mesh is repartitioned (number of processors is changed) the user will have to rewrite the cell mesh file data so that the field data coincides with the mesh information.
Thank you very much for your help,
