Happy New Year! I'm attempting to save multiple DMPlexes to a single HDF5 file. During my solution, I make modification to the DMPlex and would like to track and store these changes as the solution progresses. Currently, I the program writes the DMPlex to the HDF5 file the first time I call DMView() but throws an error the 2nd time I call DMView() to save the modified DMPlex. In my program, I would like to save more than 2 modfied DMPlexes to the same file. My current attempt at this process is outlined below with the error message copied at the end. Any help you could give to get me over this hump is appreciated. Thank you.
