PhysX Fluid Simulation
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.

Re: PhysX Fluid Simulation in Softimage ICE
Hi there,
i've made a test scene for some experiments and finally a vid ofcause
Windows 7 64bit - SoftImage|XSI 2012 SP1 64bit - GTX680 - Latest Drivers
But i've some wired random crashes from the nvidia display driver. So i can't complete this with 7,8 million particles damn ... Maybe someone else can download the scene and test with another workstation config too see it's just me
Moderator edit: just to clarify - link to scene is included on the Vimeo page. Press "vimeo" in the lower right corner of the embedded video to get there - HB

Re: PhysX Fluid Simulation in Softimage ICE
I'm having the same problem that perryharovas was having. After setting everything up I get [PX][SPH]: Get CUDA Support Failed. I went into the NVIDIA control panel and set my PhysX processor to my Quadro 600. Any thoughts on why I might not be able to get the CUDA connection in SI? As far as I can tell my workgroup and plugin are connected correctly and I have a newer version of Microsoft Visual C++ 2010 Redistributable Package (x64) than linked to on this board.
Thanks
Thanks

Can this do static friction, no slip?

Re: PhysX Fluid Simulation in Softimage ICE
Hey, this looks very interesting, but it doesn't work at my computer. I get this message: // INFO : ICE PHYSX SPH: Succefully created PxWorld! - but the emit compound and the simulate fluid compounds in the pointclouds ICE-tree both are red.
I'm on Windows 7 and Softimage 2014 64-bit and a newer version of the C++ from your link. Am I doing something wrong, or is this not compatible?
Cheers Lukas

Re: PhysX Fluid Simulation in Softimage ICE
2014 simage seems to introduce some backward compatability changes in SDK, i will recompile libs soon to see if it is the problem or something else

Re: PhysX Fluid Simulation in Softimage ICE
that was quick - thank you
Re: PhysX Fluid Simulation in Softimage ICE
I simply get a notifications on my email from all my threads
Re: PhysX Fluid Simulation in Softimage ICE
Hello mr Core, I think this may be related: I haven't been abe to get the PhysX compounds to work on the GPU ("CUDA support failed!") since I started on the Redshift alpha (in march). Redshift uses CUDA so I also updated all drivers and CUDA-related stuff and maybe some other stuff as well at that point, hence maybe compatibility problems somewhere? That was on 2013SP1, and I still have the same problem on 2014 & 2014 SP1.
Hope this helps, Jasper

Re: PhysX Fluid Simulation in Softimage ICE
Yeah, I'm also a Redshift-alpha-tester. Maybe that could be the problem.
Re: PhysX Fluid Simulation in Softimage ICE
Has anyone figured out the "CUDA support failed!"-thing yet? I tried it today and have the same issue. Pretty fast even without the GPU-acceleration though.

Re: PhysX Fluid Simulation in Softimage ICE
Mr. Core this looks really amazing!
I just ordered a new pc so i could render stuff with redshift. Looking into it i saw the video card i ordered had physx support and i wondered if lagoa did and i ended up here. Can't wait to try it out.
And maybe it's an idea to get acces to the redshift alpha as well.

Re: PhysX Fluid Simulation in Softimage ICE
If you manage to get the physx plugin to work on a system with redshift installed, please let me know. I haven't been able to use the gpu-accelerated physx since beginning of this year (since starting redshift alpha). It could be there is some Cudarelated conflict.
(Btw, don't be fooled by the relative speed of low count sims on the cpu, once you hit the millions of particles it really starts to crawl whereas on the gpu it just blazes along. Look for the 'CUDA: PhysX World created successfully!' message in the xsi message bar.)

Re: PhysX Fluid Simulation in Softimage ICE
First of all many thanks for this compound. It's a huge timesaver and great fun to work with.
I have several SPH simulations in one scene and get the following error when more then one sim is active:
Is there a solution without restarting Si everytime I want to simulate another tree?

Re: PhysX Fluid Simulation in Softimage ICE
Seems like Mr.Core is no longer with us
I wondered, could it be that lagoa in future will support physx? Or is this not possible by the way how lagoa is constructed?
Hope someone knows.

Re: PhysX Fluid Simulation in Softimage ICE
I don't think Lagoa will ever be developed anymore. It was a child of Thiago Costa.

yeah i know.
I mailed him, hope he replies.
