Hi Continuum ! ;)

i've a few question for your simulation engine :

1__ How does it compare to solution like realflow from next limit. Is it faster.

http://www.nextlimit.com/realflow/

2__ How does it compare to blender integrated solution like mantaflow / flip fluid addon / molecular

Flip fluids : https://youtu.be/8hpqwfZah08

mantaflow : https://youtu.be/vTfGo6tWkzE

Molecular : https://youtu.be/x8Fo2slT2WA

3__ Is it GPU accelareted like embergen if not do you have a roadmap for that ? AI maybe in futur ?

Well, performance is similar to Realflow (CPU) but it is faster in some cases, and vice versa. The biggest difference is that Dyverso use's position based dynamics for fluids (I use it only in the granular solver), and I use an implicit SPH solver. The latest version includes SplishSplash (https://github.com/InteractiveComputerG ... lisHSPlasH), I haven't bench marked that against Realflow yet.

Flip fluids and Manta Flow use grid based fluids (Eular simulations), and I mainly use SPH (Lagrangian simulations). So roughly the same differences between Hybrido and Dyverso in Realflow. I don't know about Molecular.

As for GPU, yes and no. GPU is only available for the Lightwave plugin at the moment. It needs to be rewritten for Deep Fx Studio, so it will be available at a later date. I don't know what the future holds, there's a long feature request list, AI is definitely one of the things people would like to see.
