Hi @PavelBlend,

free surface (water) simulations are typically a bit faster than airflow simulations / benchmark values, as not the entire box is filled with water and the air part is not computed at all then. Free surface simulations (enable SURFACE extension) need (55+12) Byte/cell in memory (the 12 Byte/cell extra are for the extension), so 2TB VRAM will fit ~31 Billion cells. At only 50M cell resolution like in this blender video, such a cascade simulation should run close to real time on an RTX 3090. Should be fun!

Kind regards,
Moritz
