Hi Senji

The obcs assumes the inputs are on the  "irregular” grid.

I'm currently running a simulation which uses an irregular vertical grid, and generating the OBCS boundary files based on this irregular spacing. I also have a version which generates the OBCS fields based on a regular vertical grid. The irregular version is consistently breaking after about 10 simulated days,. The regular version is running fine, but I'm unsure of whether it is set up correctly.
