Location of physX gpu implementation files (for sph fluid simulation)

Hi,

I’m looking for the files containing the gpu implementation of the fluid simulation and I can’t seem to find them…
They must contain and class inheriting of the class PxvParticleSystemSim. But the only child of PxvParticleSystemSim I can find is PxsParticleSystemSim which is the cpu implementation.

I was expecting to find inside some “.cu” files but the only .cu/.cuh files I can find are the ones for the rendering.

So I’m asking if anyone has an idea of where I should look to find those files.
