SPH Implicit Viscous Forces (Beta)
With the new SPH Implicit Viscous
Forces calculation, available for both
Newtonian and Non-Newtonian fluids
FreeFlow provides an efficient way of
simulating high viscosity fluids, which
were unfeasible with the explicit
formulation due to the small
timestep.
Variable viscosity of the fluid due to its Non-Newtonian behavior.
