Description
RK3 time stepping implementation for NEMO includes at this stage dynamic and active tracers implementation, time spitting single first with 2D mode integration.
...
Implementation
RK3 implementation is split up into :
- dynamic and active tracers
- vertical physics
- barotropic mode
- mass forcing
- passive tracers
1) Barocline part
- Set up a reference : GYRE only configuration with ssh, uu_b, un_adv are set to zero at each time step, no mass forcing, constant vertical viscosity.
- Prepare advection routines
- Add advective velocities as arguments for dynadv_cen2, dynadv_ubs (flux form) and traadv routines
- Allow vertical advection de-activation dynadv_cen2, dynadv_ubs (flux form) and dynzad routines
- Change eos divhor and sshwzv interface.
- Add RK3 time stepping routines
- rk3stg deals with time integration at N+1/3, N+1/2 and N+1
- stprk3 orchestrates
2) Barotrope part TBD
