Hi all, I've been working on a simulation project involving a system of connected rigid bodies in ::GPU (using ChLinkMotorRotation and ChLinkMotorLinear). The code structure is similar to the balldrop.cpp demo, with the difference being that it involves a connected system of rigid bodies controlled by motors. I've recently encountered the following error during the simulation:
*ERROR! Sphere 440770 has invalid SD 4294967295, max is 139920.* This error occurs approximately 1 second into the simulation when the robot is already in contact with particles ( So the particle initialization went smoothly, and the rendered output seems reasonable). So, I am unsure why the particle is in an invalid subdomain. I've tried reducing the time step to a significantly smaller value (1e-7) and simplifying the mesh, but the issue persists. I previously used a V100 GPU without encountering this issue, but now I've switched to an A100 GPU. Could this somehow be related? I would appreciate your comments! -- You received this message because you are subscribed to the Google Groups "ProjectChrono" group.
