Hello,
I’ve been playing around with Maya fluids, trying to figure out how to use it. Eventually, I have a very specific problem in mind, that I would like to know if it is reasonable or not to do in Maya.
Basically I want to have fluid flow through a pipe, at some velocity v(t), which changes in time. So, I need to have some way to set the boundary conditions.
Also, I have an animation that will be placed inside the pipe, ie a solid that will be moving around and changing shape inside the pipe. I want the fluid to interact with this solid in a realistic way, and then perform visualizations of the fluid’s velocity in time.
It is very important that the fluid is incompressible and will not pass through the solid at any point. Is this something that Maya can reasonably do?
I have been playing a little bit with Maya to try to get solids to interact with liquid, and here is a basic result:

You can see though, fluid seems to be disappearing after the ball hits it, especially in the right as it is dropping down. I am sure I do not have the settings right.
Here are some of the settings I have selected:
Base Resolution: 100
Solver: Navier-Stokes
High Detail Solve: All Grids
Substeps: 1
Solver Quality: 100
Forward Advection: Yes
Conserve Mass: Yes
Density Scale: 2 (What does this do exactly?)
Surface Threshold: 0001
Any thoughts on how I can get this looking how I want it to? Also how do I make this fluid more incompressible?
Also, as a side note, what kind of simulation method does Maya use? particle-based methods or eulerian methods? I see many references to a grid so I assumed eulerian, but one method of visualization is though particles, so I wasn’t sure…
Thanks!
