aki Posted March 12, 2015 Share Posted March 12, 2015 (edited) Hello everybody I am using SandSolver which I changed from FlipSolver by gasssandforce. I have a big problem for this simulation. There are many isolated floating particles. Before colliding to other particles, some particles' movement has been almost stopped. What I did is turned flipsolver into sandsolver. checked off some advect forces in the flipsolver. I used CMIVFX's Houdini Snow Simulations tutorial. If somebody knows why the particles are floating, please give me a hint or trick. I am trying to fix this problem for several months, and I changed many parameters, but I still have the problem. This is my progress, I just cut off the ending, but I really want to fix the issue. https://www.youtube.com/watch?v=61HnIUD-01w&feature=youtu.be Thank you! tes.hipnc Edited March 12, 2015 by aki Quote Link to comment Share on other sites More sharing options...
Atom Posted March 16, 2015 Share Posted March 16, 2015 (edited) The current FLIP solver, as of R14, does not support TimeScale of non 1.0 very well. Try setting your TimeScale for the solver and the flip object back to 1.0 and re-run the simulation. Also consider opening up the Closed boundaries along the top of the tank. Turn off Y+ under Initial Data. When I did this the sim did not have any stragglers hanging out stuck in space. If you must use the current TimeScale settings to achieve your effect you can dive into the FlipSolver and "repair" all the broken TimeScale links inside the solver. I cover how to do this in my BulletTime FLIP Tank tutorial in the education section of this forum. Edited March 16, 2015 by Atom Quote Link to comment Share on other sites More sharing options...
