I am visualizing a fluid domain, so the grid that I am using is fixed in time. Storing the geometry in each .vtu file takes up a lot of storage, so I was wondering if there is a way to store the geometry only once and only update the solution data at each timestep, rather than creating a new geometry that is exactly the same at every timestep.
Thanks!

There is no way to do that directly with `vtu` or other vtk files : those formats always include geometry. Maybe some file formats are able to do what you want but I do not know which ones.

EnSight format support that, and ParaView can rely on it when using the StaticMeshPlugin:
