tracers2D Section¶

This section configures 2D tracer simulations, including diffusion, advection, and input files.

Parameter	Description
`tracers_computation`	Flag to enable/disable 2D tracer computations (`TRUE`, `FALSE`).
`start`	Start time for tracer simulation (default: `0.0`, units to be verified).
`interval`	Interval for tracer output (default: `1800 s`).
`time_integration`	Time integration scheme for tracers (`FORWARD`, `LEAPFROG`, `EULER-BF`).
`input_file`	Input file for tracers (default: `tracers.dat`).
`initialisation_file`	Initialization file for tracers.
`horizontal_diffusion_mode`	Mode for horizontal diffusion (`DEFAULT`, `NONE`, `SMAGORINSKY`, `CONSTANT`, `UPWINDING`).
`horizontal_diffusion_coefficient`	Coefficient for horizontal diffusion (default: `0.0 m²/s`).
`smagorinsky_coefficient`	Smagorinsky coefficient for tracers (default: `2.8`, dimensionless).
`upwind_coefficient`	Upwind coefficient for tracers (default: `0.1`, dimensionless).
