curveU Posted May 20, 2008 Share Posted May 20, 2008 Hi everyone, I'm trying to run a dynamic simulation with fluids and RBD objects. But some RBD objects just disappeared after a certain frame (frame 86 in my case).The scene is pretty simple, just water flash hitting some objects, and the objects stay at the bottom of the water. when I checked the detailed view of the RBD objects after it disappeared, I found that some parameters became [nan, nan, nan]. these parameters include angvel, t, vel. what does that mean? how could I fix it? If anyone could give me some hint, that would help me a lot. Thanks. Quote Link to comment Share on other sites More sharing options...
ihab Posted May 20, 2008 Share Posted May 20, 2008 hi curveU, Maybe if you increase the resolution of the fluid and/or the rbd objects (volume represetation) will fix the problem. it looks like inter penetration problem to me. also the solver substeps might help here too. Hope this helps Cheers Quote Link to comment Share on other sites More sharing options...
curveU Posted May 20, 2008 Author Share Posted May 20, 2008 hi ihab, thanks for your help. my resolution for RBD is 20x20x20, and fluid resolution is 40. Let me try it with higher resolutions today. Quote Link to comment Share on other sites More sharing options...
