Flex to SiAuthor: mr_alca @si-community
updated March 2023 — (from the zip's readme) Flex to Si is a connector to Flex (NVidia's hardware accelerated physics framework). Not all flex features are enabled, only calculation of fluids and their collision with static and dynamic geometry.

Installation : put in the same directory e.g. c:\Users\alex\Autodesk\Softimage_2015_R2-SP2\Application\Plugins\nt-x86-64\flextest\ Needs DirectX!!!

Configurable parameters include (see the archive readme for some more explanation): Fluid Mode, Max Particles, Substeps, NumIterations, Speed, Max Particle Speed, Fluid Resolution Multiplier, Fluid resolution, Collision distance, Rest offset, Shape collision margin, Particle collision margin, World Gravity, Adhesion Strength, Cohesion Force, Surface Tension, Viscosity, Vorticity, Dynamic Friction, Static Friction, Particle Friction, Drag, Lift, Damping, Static triangle mesh, Static SDF mesh, Kinematic substeps, Kinematic triangle mesh, Plane Null, Use Ground Plane.

I'm sure users will be greatful!
Already is Houdini like "made for that",
while Flip sims can also be decently fast on CPUs
but if using the GPU ( with less memory than the CPU has access to ),
there are ready made tools to split simulations, some of which have been there for a very long time.

This 17 part tutorial covers alot of ground for ocean sims
( apparently only watchable directly on YT )
