I met a post-processing problems after CFDEM running. After the coupling running, two figures will bump up and I could check the results in paraview, however, sometimes if I close the figures and paraview, the dump*.** files in the DEM/post will disappear. It happens sometimes but not always! I am not sure where is the problem. Does anyone else have the same problem, and how to fix it? Thanks so much for the help and suggestions!
