Problem with vertical velocities at tile boundaries

#1 Unread post by debcox »

Running ROMS 2.2 in 3D with MPI and partitioning in the I-direction, I get significant discontinuities in the vertical velocities at the tile boundaries.

The problem disappears if the model is tiled only in the J-direction.

Has anyone else noticed this?

After a bit more checking, I think my problem was caused by some side sponge layers I had inadvertently left in from a previous (single tile) run. When I had more than one tile in the I-direction they were being applied at the sides of every tile. Sorry about that! :oops: I guess it shows there is a need to be careful how things are defined when using MPI ...
