To change the parameters of this tab on a global level, valid for all new scenes, use the → "Preferences - Simulation: General" dialogue.

 

 

Jump to

General (A)

FPS Output

The simulation's frame rate.

Threads

Here you specify how many cores will be used for your simulations. Please also take a look at → “Simulation Threads” for more information.

Processors

This is the number of available CPUs or cores in your system. RealFlow detects active hyper-threading and displays an according number of processors.

Use max. threads

When enabled RealFlow will always use the maximum number of available threads. Please also take a look at → “Simulation Threads” for more information.

Stepping (B)

MIN substeps

Specify the minimum number of simulation steps for standard particle fluids:

  • Higher values increase simulation time, but also avoid instabilities.
  • For a fixed number of substeps use equal values for “MIN substeps” and “MAX substeps”.
MAX substeps

Specify the maximum number of simulation steps for standard particle fluids:

  • Higher values increase simulation time, but also avoid instabilities.
  • For a fixed number of substeps use equal values for “MIN substeps” and “MAX substeps”.
  • Decrease this value if “FPS Output” is large – you will see a suggestion in the “Messages” panel.

 

Please be careful with Hybrido core fluid simulations (this also applies to Dyverso simulations). Let's assume you have the following settings:

  • MAX substeps (General: Stepping) = 1
  • MAX substeps (Hybrido: Liquid – Hybrido Solver) = 3
  • In this case, a substeps value of 1 is used for the Hybrido core fluid simulation.
