- In simulations, time is subdivided into more or less small steps. The more substeps, the better the simulation.
- Dyverso's "Liquid - PBD" uses a very small number of substepsjust 2 substeps by default. With fast particles or moving objects it is very likely that the fluid literally cannot "see" the object.
- Go to RealFlow's → "Simulation Options: Dyverso" and increase Liquid - PBD Solver > MAX substeps to 5 or 8. If the object is still leaking consider values of 10 or more.
