PhysX Fluid Simulation in Softimage ICE

PhysX Fluid SimulationAuthor: Oleg Bliznuk
This ICE compound wraps a CUDA implentation of the SPH fluid algorithm and allows a very fast particle simulation of fluids on NVidia GPUs. CPU mode is also available, also rather fast and not limited by the available GPU RAM. CPU mode can be used as the default mode or as a fallback mode.

See the si-community thread linked below for details and tips on using this compound. Here's a test video by Tekano with 2 million particles.

Just guessing, but could it be, you haven't got the Microsoft Visual C++ 2010 Redistributable Package (x64) installed?

thanks, but I get this message:

' INFO : ICE PHYSX SPH: Succefully created PxWorld!

no mention of cuda , perhaps Ive managed to install the ICE compound but not the dll? I cant see the dll anywhere in the plugins

** EDIT *** UPDATE ***

ok I disabled the previous workgroup, downloaded again the archive, made a new waterfall FX workgroup and now I have 2 versions , one under Px2Si called PhysX simulate SPH and another under ICE PhysX - GigaCoreFX called PhysX simulate Fluid they are both the same compound although the Px2Si version has no execute node only outputs positions.

regardless of this , something seems to have worked - am now getting 60 fps with GPU enabled and reach only 20fps without and when enabled, have the message

' INFO : || CUDA Manager Is Obtained! Created PhysX World!

fantastic! :D

>>I have 2 versions
there are no 2 versions, just a custom node and main compound which contains custom node with some connection stuff

mamali132002
try to copy px dlls from px_dlls folder ( WITHOUT px_dlls folder, just clean dlls ) into the folder with main plugin dll ( ...\Waterfall_FX\Application\Plugins\bin\nt-x86-64 )

I do :D But in this case it's not your fault [GTX 590 crash nvidia driver with this node also, just to let you know]

decrease Max Particles Count, 590 is using only 1.5 gb videoram

Ya, I know it. But we both know it's not your fault, heh? Can you help all those people with issues that they have?

Does anyone ever ask yourself if all that speed with PhysX and all GPU stuff works so great why it's not implemented in package already? Bad and lazy programmers at Autodesk? I don't think so
