Running

Preparing to run simulations

There are several options for running simulations:

Detailed information can be found at each of the links.

Running simulations

Interactive mode

If you do not specify any arguments, the simulation will run in interactive mode. You will have access to a graphical user interface with menus and a 3D visualization of the geometry. This only works in locally compiled code or when using the singularity container.

To start in interactive mode, just run the remoll executable without arguments:

remoll

To load and visualize the default geometry, use the following macro commands:

/control/execute vis/Qt.mac

Several other visualization macros are available.

Batch mode

If you specify arguments, the simulation will run in batch mode without graphical user interface. You can specify the following arguments:

Usage:
 remoll [-g geometry] [-m macro] [-u session] [-r seed] [-t nthreads] [macro]

To execute the macro macros/runexample.mac with random seed 1234 and 4 threads, just run:

remoll -r 1234 -t 4 macros/runexample.mac

Several other example macros are available.
