JuriBryan Posted December 21, 2011 Share Posted December 21, 2011 hey i am trying to set up a liquid simulation that is driven by an existing particle system.. but i can't manage to get that working. do you guys have any tips for me? Oh and there is also a problem with the collision in my file... my particles only slide a bit on the surface instead of moving for ever even with no friction turned on... cheers.. btw the forum is amazing and you guys helped me a lot with DOPs already, so thanks;P LiqiudSimulationTest.hipnc Quote Link to comment Share on other sites More sharing options...

JuriBryan Posted December 22, 2011 Author Share Posted December 22, 2011 I want to get the velocity from my particle system to my liquid simulation... i managed to get a decent effect with the velocity node in a fluid object but i don't get the extra details in the velocity that i would get with a particle sim.. here is the hip file for that, but there is a big problem with it... when i run the simulation the fluid simply sticks on the side of the sphere and is not running down... cheers FluidSim.hipnc Quote Link to comment Share on other sites More sharing options...

3dbeing Posted December 23, 2011 Share Posted December 23, 2011 (edited) anyone got a idea what is going wrong there? What is it that velocity impulse is doing? Velocity Impulse Force Impulse is force * time and thus corresponds to a change in momentum... An object will receive force corresponding to the impulse divided by the timestep, thereby causing the object to gain the specified momentum in a single simulation step. Also if you notice on the noise dop, the output is green, this indicates it be plugged into a green input. Finally you have your force set to set initial, prolly you want it set to set always then animate it's values. have a look Edited December 23, 2011 by 3dbeing Quote Link to comment Share on other sites More sharing options...
