I’m running the Blender 2.40 alpha1 version on a pentium 4, under Windows XP, and I’m currently checking the fluid simulator.
It works, but I have some problems too.
I will make my own post to let people answer your’s.
I will try to explain the settings:
I use a mesh (a cube or a sphere, no matter) as liquid source.
If you set it as liquid, it will only fall like a drop. So if you want to pour some liquid continuously, select Inflow.
Make a container for the simulation by selecting Domain (a deformed cube). Only the bound box will be used.
Now, you can add a object set as Obstacle.
You can also set a directory and a file prefix name for the generated files.
Then select the Domain object and click on BAKE button. It should launch a simulation (a progressing colored bar is displayed in the top right corner of the screen).
