Prefs - Command Line

With the help of this panel it is possible to configure a command line simulation. The parameters do not have any effect on GUI simulations.

Range

Same as scene

When this option is checked the command line simulation's range is exactly the same as the one adjusted on the timeline. To specify a new range, disable “Same as scene” and enter your values in the unlocked fields below.

Frame begin/Frame end

If you want to perform a simulation within a specified range only, uncheck “Same as scene” and enter start and stop frames. Please make sure that “Frame begin” is smaller than “Frame end” to get a plausible result. “Frame begin” also needs to be adjusted if you want to resume a simulation from a certain point in time.

Threads

Same as scene

This option is enabled by default and the number of threads is read from the scene's “Simulation options”. In some cases, for example with very low particle counts, it is often helpful to use only one or two threads to accelerate the simulation. If you disable the checkbox the “Threads” field becomes editable.

Threads

To enter a new number of threads you have to disable “Same as scene” first. Then, you can enter a new value.

Args

None

With this option enabled, RealFlow will perform a “normal” simulation using the current scene's settings; the simulation performs exactly the same way as if you were executing it inside the GUI version – but faster.

Reset

When “Reset” is active, the simulation will be reset before it finally starts. All previously cached data will be overwritten.

Use cache

When this argument is enabled RealFlow will load all available cache files for the start frame (see “Range” field) directly before the simulation starts. This option has to be active if you want to resume from an interrupted simulation. Without "Use cache", the simulation simply starts from the specified frame without reading previously stored data.

Mesh

If you only want to perform the creation of meshes from already cached data please choose this mode. In this case, the “Command Line” version will not simulate again and already existing files will be kept.
