I tried that with the previous version and it had no affect whatsoever. I will try again with the new one.
I already have that set up from when I was trying to troubleshoot the first version. It made no difference whatsoever. I think the problem is that on my nVidia control panel I can only select the OpenGL device for my application, whereas I need to select the OpenCL device, but there is no setting for that.
dForce simulation settings lists three OpenCL devices. My 1080Ti, my Intel HD630 and the CPU. With dForce I can see what is available and select the correct one. It might be better if Fludios was to make the relevant OpenCL call to get the list of devices available and then list them. Just stating "GPU" and "GPU 2" is not very obvious for the user which one to pick.
FLUIDOS lists always two GPUs, but if the system has only one, whichever GPU the user chooses, the plugin will take the available.
This is because only the engine itself has access to OpenCL. There are two dll files in the package, one is the abFluidos.dll, the one that plugs in to Daz Studio. This abFluidos.dll, in turn, calls the fluidsim.dll, the engine. But the calls are only after the user runs the simulation. Thus, the abFluidos is unaware of the actual OpenCL devices. It only says the engine to try to find a second GPU when the user chooses GPU 2. If the engine don't find it, then uses the first one.
ok, I can see why a list would be tricky, but obviously would be desirable. Unfortunately the engine picks the same GPU for me using with GPU or GPU 2, I have no idea why, because it does use the 1080Ti when the on board GPU has had its drivers removed.
Then, as the on board GPU drivers had removed, OpenCL in the engine can only see a GPU.
But it's not as important what OpenCL device is used, as long as it works, because there is no great difference between devices perfomance for the engine, at least for the current version (my plan is to optimize the engine as I update the plugin).
From the tests I have done, then it is true that the GPU is heavily under utilized, so you are right that a good GPU is not that important. For me it is important because one GPU does not work at all, but at least I still have my workaround to stop it trying to use the Intel GPU.
I suggest though that you first optimize the use of the CPU, rather than the GPU. The current engine only seems to use 1 thread, and that is a shame as most people have 2-4 cores with 1-2 threads to use in each, and most will sit idle when running a simulation. A multi-threaded engine would speed up simulations for all, not just those with a decent GPU. I have no idea how much work it would be for you to make the engine multi-threaded.
Of course, multithreading is a priority objective.
By the way, the CPU option in Preferred Device is an OpenCL option device (parallel programming). In fact, some computers could run simulations faster using CPU OpenCL than GPU OpenCL..
On the other hand, if you set Enable OpenCL to Off, then, really only one CPU core will be working and the simulations running are slower (but not too much).
This was a animated short using the fludios plugin. it was a little tricky but i was able to use the plugin for the drinking glass the trick was I had to parent the domain and the mesher to the glass so it would move with the characters hand .. Still didn't come out as good as I hoped but its a start in using it in short fiilms
Your water effect is pretty believable, Ivy.
Nice animation. I love the sound effects!
Thanks for watching guys . Fluidos is going to be a great plugin tool for props fill ins in short animation. I can't wait to see whats next :)
I think that was very well done. Spooky!
That was a great animation Ivy.
Thought I'd share what I've been learning to do with Fluidos. These are my two best so far. The first one uses a Fluidos source with an upward water flow with a 100 velocity. I did not include a sink so it builds up in the bottom of the domain. I used an Iray water shader from Sickle Yield's Rigged Water Iray 2. The second one uses 3 spheres as the source, has a 0.375 cell size (to minimize leakage through the glass sides) and has diffuse particles turned on. I used the Easy Liquid liqueur shader. Both simulations used anisotropic settings.
(If animation stops, reload the page or click on the image)
nice work. I like the glass falling that looks amazing
Wow, that water is cool!!!
Can you make the glass break, too? I guess that would be difficult, making the broken pieces and shards.

I had the same thought but didn't have a good way to do it. I seem to remember coming across a product in recent weeks that showed a shattered coffee cup but at the time I didn't envision needing it. EDIT: Upon reflection, it was a Blender cell fracture add-on
Cool, but I'm not into Blender. Maybe we'll have that in DS someday.
Dana
The glass animation is awesome!
Yes, someday...
That looks great, Alberto! And great work to you too, Ivy! For some reason my previous post disappeared!
Alberto... Are you going to add more awesomeness to the greatness of your plugin?
Yes, this is my plan.
The user's manual:
11. Call the simulator (menu Edit – Run Fluid Simulation).
Can't find it :(
Did you register the plugin with your serial number?

Dumb question: how you installed it?
* needs a fainting smiley ASAP *
I have issues figuring out how to make a fluidos source more slim/small. When I lover the marker particle size the particles get smaller but the animation is really scuffed.
You have to reduce the cell size and the source size too.
Imago could give you more advices, he did many tests with slim sources:
Here I am to help you, Surody!
Alberto is right, but just those adjustements won't suffice for a nice, narrow jet.
Here's what you have to do:
Create a Domain and a Source. In the Source parameters enable "Is Cuboid" and make all three sizes like 0.050 or less. Set your preferred velocity as you please but use only one direction. Since the source is going to be very small, I suggest you to create a "Placeholder" using a plane and parenting the source to it (Not the opposite!), this way you can see where it is and reposition it.
Now, in the domain set the Cell Size to 0.50 (Lower parameters will take way longer calculation times), Subdivision 2, Marker Particle Scale 3 (you can play a bit with that to change results), Surface Smoothing Value 1, Smoothing interation 10 to 15 (depends on how much you want the drops to be one single stream) CFL Condition 2 and PIC/FLIP Ratio 1.
These are the basic settings for a narrow, unbroken single stream of water. No need to use doubled FPS, these will work fine with 30 FPS!
If you make 10 or 15 identical Sources and position them in the right array, you can make a really nice shower. You can also make a water-pistol spray adding the Diffuse particles.
One thing to keep in mind is that the drops will look "crazy" once they lay on a static surface like the bottom of the domain on a horizontal obstacle. To mitigate it (if you need) it's necessary to increase Subdivision level at cost of longer calculations. A solution for showering scenes is to create a very flat cube on the bottom of the domain, make it Fluid Mass and add a small Sink (matching incoming fluid amount) on the side to cancel the crazy drops and also have the effect of the water dripping on the wet surface.
Starting from these base values, it's enough increase the size of the source to have a thicker flow, for example a bottle or a kettle pouring fluid.
I have seen a few people reference videos, but I am not finding a solid Fluidos tutorial video. Is there one?
I am fairly new with more advanced features of this, but I am trying to understand how to have the fluid interact with my character and structures. Right now the water simply falls through the character and floor.
There are two video tutorials in your Daz library, at "/General/Alvin Bémar/FLUIDOS for Daz Studio/"
