MartinuZ Posted April 28, 2014 Share Posted April 28, 2014 Hi, I'm getting some weird simulation errors, see attached screenshots. I have 5 objects that are traveling down a path and emitting smoke in a pyro container, but at a certain frame the smoke just explodes and houdini will freeze if left simulating (if i'm fast i can escape the sim) does this look familiar to someone? I've tried increasing substeps on the autodop network but that doesn't help.. regards, Martijn Quote Link to comment Share on other sites More sharing options...
MartinuZ Posted April 28, 2014 Author Share Posted April 28, 2014 (edited) It seems my problem is solved by increasing max substeps on the pyrosolver to 2 and the cfl condition to 3.. I also forgot to mention that the emitters travel through the smoke in a vortex like motion, so I'm guessing that when a voxel gets 'overloaded' by smoke it will destabilize the simulation. Is this a correct assumption? edit:well it seems I cheered to soon, still getting the same errors.. so I'd still like to know what causes this.. edit2: my problem is the same as here: http://forums.odforce.net/topic/18923-vortex-force-blowing-up-smoke-sim/ the vortex was causing it, increasing the radius did help Edited April 28, 2014 by MartinuZ Quote Link to comment Share on other sites More sharing options...
