[MITgcm-support] variables (.)_F1 in obcs_calc.F

[Duran Camejo, Mario FORNATL, SP]

Hello Martin,

I hadn't got an answer yet, thank you very much for replying!

I will try to explain my question a little better. I'm using MITgcm although, as you say, it is not meant to simulated watercrafts moving in the ocean, because 
I'm interested in the evolution of the wakes (after a watercraft) and for that  I think MITgcm is an extraordinary tool. The way to simulate a watercraft 
accelerating through a fixed box in the ocean is by "injecting momentum" to the fluid inside the box, namely, setting some additional velocity in a small parcel of the fluid 
every time step and updating the boundary conditions for the zonal velocity in the west every time step too (watercraft is moving east to west which is equivalent to 
assume that the fluid is moving west to east and the watercraft is at rest), whereas keeping Orlanski open boundary conditions in the east to allow the free development 
of the wakes. Maybe it wouldn't be necessary to go through the F1 variables for updating the BC in the west because the time-evolving BC there might be 
straightforwardly calculated in obcs_calc.F. Any suggestion will be greatly appreciated!

Anyway I will take a look to “verification/exp4”. 

Best regards,
Mario

Mario,

did you get an answer? I am afraid that your question is not clear.
- the MITgcm is not meant to simulated watercrafts moving in the ocean, you could probably used some of the technology and introduce fixed geometry representing a watercraft, but I am sure that there is better software for that
- the *_F1 variables are passed to the model via MPI from a parent model into which the current model is nested. This is a feature that is not used very often and I don’t know how well this is maintained. For a more typical application of the obcs-packace see “verification/exp4”
