Help Mixing Fluids

[josemendez]

Hey Jose,

I've been able to progress pretty well, however I got a question, and maybe I didnt know the correct wording to see it in the manual, but when I pour 2 liquids inside a glass, they bounce really high up, what variable would I need to change to stop the bounciness of the fluids?

Bounciness is not explicitly modeled in Obi (so there's no bounciness parameter anywhere). However, compressible fluids can bounce due to lack of convergence.

You can increase simulation quality by using more substeps and/or iterations. This will increase simulation quality, making fluid less compressible and hence, less "bouncy". See: http://obi.virtualmethodstudio.com/manua...gence.html

Quote from the very end of that page:

Takeaway message from this section: If your rope/cloth/softbody/fluid is too stretchy or bouncy, you should try:

Increasing the amount of substeps in the updater.
Increasing the amount of constraint iterations.
Decreasing Unity's fixed timestep.
