Transport
This parameter can be set either to
'FARGO' or to 'STANDARD' to define which kind of azimuthal advection
algorithm has to be used. In the 'STANDARD' case, the azimuthal
advection is performed in a standard way, and the CFL criterion
includes the full azimuthal velocity. In the 'FARGO' case, the FARGO
algorithm described in Masset
(2000) is applied, which relieves the CFL condition and allows a
much larger time step and a faster calculation. The Transport
parameter defaults to 'FARGO'. It can be set to 'STANDARD' for
comparison and benchmarking purposes.
