One mesh for time dependent variable

[Uswald]

I've got a time dependent vector field on a unstructured mesh. The mesh is not time dependent. I want to store the field at eac time iteration. So when I write the field I write the mesh also. Is it possible to store the mesh once and not at each iteration? If yes, how can it be done?

Yes, I believe this is possible. It requires some care so that down-stream consumers (e.g. something like VisIt) can operate normally without having to do anything special to read and consumer your data.

I think this may be possible only on the PDB driver. So, put the mesh in one file like maybe mesh.silo with name vecmesh. Then, put the time varying vector field in each of their own files like maybe vec000.silo, vec001.silo etc. When you call DBPutUcdvar() to put the vector field in those files, specify the meshname as mesh.silo:vecmesh.

I don't think the HDF5 driver was designed to support the <file>:<objname> referencing mechanism.

I believe that will work. I should create an example test case for this.

I did what you proposed, but when I open the results in Visit the following error happen: "There was an error opening vec*.silo database. It may be an invalid file. VisIt tried using the following file format readers to open the file: Silo"

Can you attach file?

Here is the mesh file and the vector field file.
