I would like to add support for this, but don’t currently have any funding to do it. The basic structure of vtkCellGrid makes a lot of it simple, but taking account of some things will involve more than just a few hours to design and implement tests:
- shared arrays across partitions in a vtkPartitionedDataSetCollection of cell-grids;
- handling distributed data and ghost-cell computation; and
- re-use of topological connectivity across ranges of timesteps.
The basic implementation should be pretty simple and only a day or two of effort.
