I just know physx today. Wanna learn it. But failed to find any tutorial for beginner.
PhysX Fluid Demo seems helpful. But the download link is not available anymore.
I don’t think that source code of the Fluid demo will be/was ever released.
However, there is more advanced, PhysX 3 based fluid demo - Fluid Sandbox

I would recommend to contact its author.
