Paraview-storing time series of attributes without saving mesh
 

Hey everyone
I am using a mesh consisting of more than 20 million nodes, and running an analysis that will take more than 10000 iterations. Generally to store a series of dataset attributes for a number of iterations, the convention is to save as
file.0000.vtk
file.0001.vtk
file.0002.vtk etc.
But this would require me to rewrite the point coordinates, and connectivity of mesh, for every file, leading to heavy time overhead.

Is there any way I can only write the geometry/mesh data once, and then for every iteration, write only the attribute values?
Any help would be greatly appreciated!
