Dear Bonnie Thanks for your mail and the files..I notice that these files are for generating sponge fields and they are quite old (use Eugene release of FMS). I was able to generate sponge fields with regrid_3d as Matt suggested a long time ago but the problem is to bring them into mom4. I have been looking at the code mom4/ocean_aparam/sources/sponge/ocean_sponges.F90 carefully. I notice that you have done something quite clever like finding out if a local_domain has any sponge calls at all (the use of col) and setting sponges_anywhere =.true. if there are points with in a local_domain which has sponging. I have a basic problem with this..Wouldnt trying to do sponges only on a few pe's give rise to "load imbalance"?..what we gain in pe calculations may be lost at a "sync" when we update_domains. If I strip this part out and let every point in the full domain do a sponge, would I be shooting myself somewhere? I rewrote a lot of the sponge code to use Matt's "init_external_field" like he does in ocean_flux.F90 to bring in time-dependent sponge values but I'd like this point cleared before I go further.. Thanks.
