[MITgcm-support] from C- to A-grid (particle tracking)

[Wang, Jinbo (329B)]

Hi Andrea,

  You may want to take a look at https://github.com/jinbow/octopus. It is written to be used with MITgcm output, and parallelized with openmp. Some examples of the particle tracking simulation with SOSE can be found here: http://pordlabs.ucsd.edu/jinbo/main/movie-olp-DP-SO6-Iter60.html
  One advantage of this code is the light-weight and independence of other packages. The disadvantage is that it does not use MPI, so cannot be scaled up as done in FLT package.

    Dear all,
    I am in the process of setting up some particle tracking experiments. 
    After some research and some thinking about my needs, I am inclined to 
    use an offline tool rather than the MITgcm flt package, most likely CMS 
    (https://www.rsmas.miami.edu/users/cparis/oss.html).
    
    In order to use CMS, I need to interpolate the MITgcm results from my 
    native curvilinear C-grid to the non curvilinear, non rotated A-grid 
    which CMS requires. My questions then are:
    - is there a way to do this interpolation maintaining the flow (at least 
    approximately) non divergent? (with complex boundaries)
    - does anyone have any suggestion on working with MITgcm+CMS, or more in 
    general with MITgcm+particle tracking?
    
    The alternative is to implement C-grids in CMS, which would be 
    interesting but I'm not yet sure it's realistic.
    
    Thanks, Andrea

    PS: To answer the obvious question one may have: I think that the flt 
    package is not the right tool for me, since I would like to have several 
    particles (>>1000), doing repeated experiments over the same period of 
    time, in a rather small domain. I think that an offline tool is in this 
    case not only much faster, but also much more flexible.
