Cool, thanks.
Yeah, I think I'll give the 960 a go, price is reasonable. And an ssd.
So the ssd will come in to play in terms of read/write speed of caches?
re overclocking will look into that but even a 30% decrease in sim calc time via gpu would be good.

Hi there
So today I bought a second hand dell 3600 xeon quad core 3.6ghz with 32 gig ram , unfortunately it only has a quadro 600 graphics card in it.
It's running windows 7 professional 64 bit.
Old I know but solidly built and at least half the price of buying something new with those specs.
I've migrated from a variety of mac products none of which were particularly good at running Houdini.
My question is which graphics card should i be looking at to reduce my processing time for fluid simulations.
Looking at the sidefx recommended specs for graphics cards it seems to say I could only use (within my price range) geforce 400 or 500 series cards as they support opencl.
Does this mean later cards don't support opencl and won't make any impact on sim processing time?
What would I gain from buying other cards which are listed as being supported?
If I replace the quadro 600 my main aim would be to reduce the processing time for simulations.
Any advice much appreciated.
thanks nigel.

Hi There
SPH is called particle fluid object and solver they are still there just not on the shelf.
I'm working with these at the moment and I think the results are better than flip for small scale fluids.
If you use vdb from particles and convert vdb to polygon soup there seems to be a fair amount of control re meshing.
Re your problem with fluid colliding outside of the glass, do mean it's colliding with the outside edge of your collision volume?

Hi there
I've been using the flip solver with vdb it seems to be going well but I will have a look at the particle fluid solver also and see what I get.
Anybody know if there's a guide somewhere to setting up the dop network and inter relationships from scratch rather than with the shelf tools?
thanks

Thanks, after initial readings I thought Flip fluids were more suited to large bodies of water rather than for example a glass of water but having read further it seems maybe not. I'll have a play.

So flip would work better than sph for fluid in a glass type simulations?
I was under the impression after reading descriptions that sph would still be the best way to go with this.
I work predominantly with small scale fluids.

Hi There
I've been using sph fluid particle sim in blender and would like to try the same in Houdini but I can't figure out how to build it up.
Is anybody able to show me the correct node set up for this please?
Any help much appreciated.
thanks

Hi there
I'm new to Houdini and am using apprentice to learn.
I've been using sph fluid particle simulation in Blender and want to trial the same in Houdini.
However I can't for the life of me see how to set it up, the shelf tools only create flip fluids and I can't figure out how to set it up manually?
Any advice would be much appreciated.
thanks
