-a
|
every
DT, the mesh
mass and angular momentum are written to the standard output. |
-b
|
Initialize
properly the azimuthal velocity so that the centrifugal balance is
enforced to the platform accuracy,
regardless of the resolution (the method to do that is described in
Masset & Ogilvie 2004, ApJ, 615, 1000, in section 2.4).
|
-c
|
Sloppy
CFL condition. The CFL timestep limit is usually checked after every
hydro timestep. There may be many such timesteps over a time interval
DT. If the -c
flag is set, the CFL timestep limit is evaluated only every DT. This
may be relevant for low to medium mass planet with reasonnable
smoothing lengths, which do not strongly perturb the flow. |
-d
|
Print
some debugging information on the standard output after every timestep,
which gives the CFL most restricting zone and the reason for the limit
(advection speed, sound speed, viscosity or shear).
|
-e
|
Activate
EU
test problem torque file output.
|
-f
scaling
|
Scale
the density array by `scaling'
before running. It may be used during a restart to get a lighter or
heavier disk. It can not be used twice for two consecutive restarts.
|
-i
|
The
unperturbed surface density profile is sometimes needed by the code (e.g. to impose the surface density
at the boundaries for the non-reflecting boundary condition). When
setting the -i
flag, instead of using the analytic profile given by Sigma0, SigmaProfile
and possibly CavityRadius and CavityRatio, the code uses the surface
density profile at restart as the reference.
|
-m
|
Merge
output from different processes (MPI only). Unless each processor has a
different filesystem and does not see the other processors filesystems,
you should use this flag. The
output is then strictly similar to a sequential run output.
|
-n
|
Do
not start a run. Just read the parameter file, output any information
possibly provided by other switches (such as -v), and
quit.
|
-o
outputdir
|
Overrides
the output directory specified by the parameter file variable Outputdir.
|
-p
|
Give
some basic profiling information every DT.
|
-s
number
|
Restart
simulation, using output #number as
initial conditions.
|
-t
|
Provide
some CPU usage information at each output. You can deduce an estimate
of the total CPU consumption of a run by extrapolating the indications
at the begining. Remember however that especially with the FARGO
algorithm the time step may be strongly variable with time.
|
-v
|
Verbose
mode. Some information is provided before the run starts, including
expected disk usage, some physical properties of the disk, etc. Note
that some of this information is obsolete, and may be inaccurate.
|
-z
|
Fake sequential run. Cumulative
operation in MPI (such as torque integral over the mesh) may give
slightly different results in sequential and MPI calculations, due to
the random ordering of the sum terms in this last case. Using the -z
flag in an MPI calculation ensures that the sum result is strictly the
same as for a sequential run.
|
-(0-9)
|
Write
initial (or restart) HD variables and proceed to nth following output,
then quit. The number of outputs provided by the parameter file
variables Ntot and Ninterm
is therefore discarded (although Ninterm is
used to proceed between successive outputs). This option must stand
alone on one switch (-va -4 is legal, -v4a is not).
