Hi Sun, Unfortunately, there is no run-time visualization for DEM-E simulations yet, because those simulations are probably too large to efficiently render real-time anyway. You need to render the movie using the output CSV and VTK files.
To have a quick start, you can use ParaView <https://www.paraview.org/>. VTK files for the mesh can be directly loaded into ParaView for display. CSV files give the time series of the XYZ coordinates of component spheres (if you used *WriteSphereFile *to output them, that is) and their radius. I usually load the file, then use *TableToPoints *filter to generate the points in space based on the *x,y,z* columns, then use *glyph *filter to render those points as various-sized spheres based on the radius column *r* .
