When enabled, RealFlow | Cinema 4D applies default settings. These default values work for most projects with PDB or SPH fluids, but for other materials (granular, viscous, etc.) it is normally necessary to apply custom settings. This also applies to simulations with collision geometry involved.
Min | Max Substeps
Here you find the minimum and maximum numbers of simulation steps. Substeps play an important role for collision detection. If you see particles going through a solid object
