I am solving an unsteady fluid mechanics problems with a large mesh (almost 9 million cells). I am using two different methods to save the timeseries data. One is through write and the other with write_checkpoint. I am storing these timeseries data in two formats primarily for visualization and pos…

You are right, in write checkpoint, you cannot reuse the mesh. Have you tried using HDF5File (it is not possible to open in paraview, But can do check pointing: https://bitbucket.org/fenics-project/dolfin/raw/946dbd3e268dc20c64778eb5b734941ca5c343e5/python/test/unit/io/test_HDF5_series.py ) By brows…
