Just tested one of the PhysX3 demos of the code sample pack (host_api/PhysX3/Fluids/) with the DEV version I'm working on (v0.6.3.18) and now collisions of a fluid with a static mesh work fine. In the following screenshot, two particle emitters are inside a mesh box:
With prev versions, collisions were not handled with GPU fluids and CPU fluids led to a crash...
