[MITgcm-support] How to specify location in parallel field?

[David Hebert]

Hello all,

I would like to set the velocity field to a specific value at a specific 
location in the code (say, global gridpoint x,y,z). If I understand 
properly, in a parallel run each processor has its own range of elements 
with indices that are not necessarily the same as global indicies. Is 
there a function out there or a method I haven't found yet that will 
allow me to specify a global gridpoint and convert to local processor 
and local gridpoint?

Thanks,

David
