Let’s say you do a fluid sim where the fluid flows into a glass bowl which is set as an Obstacle. In my attempt, where the fluid fits against the glass bowl, through the glass you see that there are always a uneven undulating sides where the fluid presses against the glass even at high res fluid. So I looked at the Blender Cookie tutorial “Create a Realistic Water Sim” and it shows how you manually smooth this ripple - but that was for 1 frame…what if you have hundreds of frames of fluid to smooth? Is there a setting or automated way to smooth it over many frames?
Thanks!
I thought I’d try this and here are my results. I wondered if some of the anomalies were related to topology. So I used an Icosphere as the obstacle. This is a triangle based obstacle because the fluid is triangle based as well. This way were are not comparing quads against triangles during collision. I also upped my resolution to 2GB then I increased Smooth (the fluid parameter, not a modifier or tool) from 1.0 to 3.0. I let the sim bake overnight and the output looks ok without any tricks at all. No boolean, smooth or shrinkwrap involved in these images.
Wow. So let’s say it wasn’t a sphere, but a custom shape like human face model that you had modeled in quads… would you need to convert that human face from quads to triangles to get good results too?
I really think it is the higher resolution and the increased smooth factor. But you could give the human face a try. Convert it to triangles before you bake.
