Console Arguments

Instead of using the parameter file param.dat, some arguments can also be passed as console arguments. The console arguments have the highest priority and are overwriting the arguments of the param.dat file. The options are:

  • -dt <f>: Time step in days

  • -ei <i>: Energy output interval

  • -ci <i>: Coordinates output interval

  • -I <i>: Number of integration steps

  • -n1 <f>: Value of n1

  • -n2 <f>: Value of n2

  • -ndev <i>: Number of devices to use

  • -dev <i>: Device number

  • -in <s>: Input file name

  • -out <s>: Output name

  • -R <i>: Restart a simulation at time step i

  • -TP <i>: Test Particle mode i = 0, treat all bodies the same way, i = 1: small bodies don’t affect big bodies.

  • -M <s>: name of file, containing a list of the directories for the multi simulation mode.

  • -Nmin <i>: Minimal number of bodies in the simulation, not including test particles.

  • -NminTP <i>: Minimal number of test particles in the simulation.

  • -SIO <i>: Order of symplectic integrator, The options are 2, 4 or 6.

  • -aeN <s>: Name of the aeCount grid

  • -t <f>: Start time of the simulation in years

  • -MT <i>: Number of simulations in TTV calculations

  • -sl <i>: Symplectic recursion levels

  • -sls <i>: Symplectic recursion sub steps

  • -collPrec <f>: Collision Precision

  • -collTshift <f>: Collision Time Shift

  • -GR <i>: Use GR

  • -Nomp <i>: Number of parallel CPU cores to use. Only available in CPU version of GENGA

Here i means an integer, f a floating point value, and s a string.
