[MITgcm-support] Loading a new variable

[Nicolas Grisouard]

Hi,

I think I tried like a year ago (not sure what the exact package was  
though). I might have not gotten it right but I came to the  
conclusion that I only had 2 options: either to set a constant  
forcing (which seems to be te case in exp4, but which is not the case  
in my experiment) or to reload a new file at each time step, which  
was nearly doubling the computing time.

My idea is to load the spatial stucture of the forcing once and for  
all, like tRef, and then to apply a time propagator at each time  
step. The spatial structure as no simple analytical formulation,  
unlike the time propagator which is simply exp(iwt). Following Jody's  
links, I am modifying load_ref_files.F to add a new variable and I  
think it should work... shouldn't it?

Nico.
