- With a value of 1.0, the fluid will not move more than 1 grid cell the distance of 1 particle diameter in the current time step.
- With values smaller than 1.0, the fluid can cover a longer distance within a single step – the solver is less strict.
Max neighbors
This parameter is only relevant for → GPU simulations. Dyverso looks for neighbours to create the links and constraints between them. By default, 100 particles will be taken into consideration:
- The less neighbours, the faster the simulation, but you might see stability problems.
- We recommend using the pre-adjusted value.
Use Geometry Velocity
When enabled RealFlow will adjust the simulation's substeps to get a correct fluid-object interaction behaviour:
...
- Higher values increase simulation time and can time but also maybe lead to instabilities. We recommend moderate increases of just a few substeps.
- For a fixed number of substeps use equal values for “MIN substeps” and “MAX substeps”.
- The default value normally provides the best ratio between speed and accuracy.

- Higher values increase simulation time and can time but also maybe lead to instabilities. Try using values around the default setting.
- For a fixed number of substeps use equal values for “MIN substeps” and “MAX substeps”.
- The default value normally provides the best ratio between speed and accuracy.
