Hello all! I am currently working on VIPER rover terramechanics SPH simulations using the the ChTireTestRig and have been struggling to generate images and animations that include the wheel, soil and complete rig mechanism.
I was previously using *ParaView*, but `ChTireTestRig` doesn't have a built-in function to save VTK files of the mechanism itself. Because of this, my animations only showed a floating, single wheel gliding through the soil. Let's just say that for the purpose of presenting results to people who aren't familiar with terramechanics single-wheel tests, it looks a bit mind-boggling! Haha. So, I decided to try *Blender*, since I've seen beautiful images and animations on SBEL's website and knew, from SBEL's NASA Workshop slides, that they were generated there. However, now I have the opposite problem: I can only export the solids, not the soil. Here is what I have tried so far to bridge the gap: - *Exporting soil from ParaView to Blender:* I tried saving the soil as an animated scene in ParaView, but it only exports in the .vtk.js extension, which Blender doesn't support. - *Using SciBlender:* I managed to export the soil in other formats, and while it generates files for all timesteps, Blender only reads them as individual static scenes. - *StopMotionOBJ:* I tried using this add-on to handle the time sequence, but I couldn't get it to show in the export/import menu, despite installing it. - *Exporting the mechanism from Blender to ParaView:* I attempted to bring the rig into ParaView, but I couldn't export it as an animated scene. Currently, the only workaround I have is generating static images in ParaView by exporting the mechanism from Blender as a .glb file at the exact timestep I need. Unfortunately, this means I cannot generate animations. I apologize for the long text, but I thought it was important to share what hasn't worked. Could anyone provide some guidance or a recommended workflow on how to render animations that include the soil, the wheel, and the rig mechanism all together?
