Fluidos 2

Hi all.

I use this plugin for fluid simulation. Great product. But I have a few technical questions.

1. How to make a simulation on the GPU? So that I do not click, the CPU load is 100% but not the GPU. My specs: i9 9900k, 2x 2080ti

2. Example: A jet of water is directed at the character. The character moves, trying to hide from the water jet. If the character moves abruptly, then the simulation of the liquid, as if it does not keep up with the movements of the character. The liquid passes through the character in places. I'm doing a 24 fps animation. Do I need to increase the fps for the simulation, or do I need to adjust something else?

I also attach a screenshot with the settings

    Hi, Jovanni:

    1. Currently, Fluidos II doesn't use intensively the GPU.
    2. You can increase the FPS in the domain, or reduce a little more the CFL condition number. Another useful thing is to increase the thicken parameter in the chararacter. Or to use an invisible geoshell of the character as the actual solid obstacle (and set the character itself as ignored)

    Thanks for your reply. A small clarification. If the simulation uses CPU cores.
    Will the simulation be faster with a Threadripper 3990x (64 cores) for example?

    Yes, it will. See this post: https://www.daz3d.com/forums/discussion/comment/5719286/#Comment_5719286
