hi，Ruochun Thank you for your answer. I will try this method and wish you success in your work Sun

You need to render the movie using the output CSV and VTK files. To have a quick start, you can use ParaView. 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.

How can I visualize the simulation? Just like this example: movie for this demo here Good luck with your project. Thank you, Sun 在2024年3月4日星期一 UTC+8 22:02:49<Zed Sun> 写道： Thank you for your solution. I will give it a try. 在2024年3月4日星期一 UTC+8 20:59:37<Ruochun Zhang> 写道： Hi Sun, Just to add to what Dan suggested... You can find the "new DEM solution" for irregular soil grains in Chrono DEM-E, and the demo script is here. You can use it in Python as well: Please refer to DEM-E's readme document. Check out the rendering/movie for this demo here.
