  1. i will try it and see how it will looks but i guess i not completely stick or slide .. something between
  2. isn't slip on collision will make it more sliding ? cause i want it to stick and if i did set to 0.1 it will have more sliding attribute than if its OFF.. am i right ?
  3. yea i found it but since i'm working on small scale sim the tweaking is too hard and rare when it stick
  4. i'm trying to make a honey simulation on a pancakes i have set everything except i dont know how to make the honey stick on the static object, i want it to keep falling but a thin layer of the honey stick on the pancakes anyone can help me to do this ? i'm using Houdini 16
  5. wondering how to make a sphere move in spiral way in X,Z axis only , either starting form the middle and expanding outside or vice versa, so i can emit from it flip simulation
  6. 1) if i used polyreduce to the object wont affect the collision shape on the surface of the fluid ? 2) using 0.2 particle separation it will give you small jump reaction to the fluid but mesh will be low res if i increased the particle separation the jumping part of the fluid will be higher 3) adding -50 initial force to the Y Axis will do more splash but when you do composite the strawberry velocity will be too fast not a gravity speed 4) adding the ground cause i thought when the strawbs penetrating the bottom of the fluid it will create stronger reaction to the fluid so i added the ground to reduce the reaction 5) i tried up to 600 viscosity down to 25 didnt help 6)using openCL for faster GPU, i have GTX 750 TI so far these methods just for playing around not for rendering actual commercial or flip shots Thanks for help if you found any other solution please tell me i appreciate your tries
  7. i have a problem with the splash that comes from collision object into the flip fluid ,i created a flat tank and i imported a strawberry obj and make it to Hero RBD with volume collision , bu tas you see the splash is too weak and the feedback of the fluid jumping after the collision is too high, and i got tired trying to solve it to look realistic particle separation : 0.045 = almost 10 mil density of the fluid : 1100 collision feedback scale : 0 collision force scale : 1 viscosity of fluid: 35 surface extrapolation: 0.001 velocity transfer: swirly kernal surface tension: 10 vorticity : on preservation rate: 0.1 use friction and bounce in solver is off Dop SUbsteps : 2 falling strawberries density : 100 solver type = RBD Houdini version : 16.0.621 hip file included + obj strawberry will be thankful if anyone helped me reference splashes: in this video the reference for the jumping fluid after the collision in the youtube video ate the 0:17 just a simple splash close to crown splash Chocolate_sim.rar
  8. Thanks Atom i will go through it
  9. hey houdini users, i'm doing a flip simulation for strawberry falling into chocolate but i cant figure out the right surface tension for viscous fluid and i don't know how houdini calculate Surface Tension or how to find the relation between liquid mass-density and surface tension ? and also does houdini calculate it in millinewton per meter ?
