Re: Blow up problems for an Internal Tide case

Well, gridpak is ancient and the manual is even older. There's a link to the manual from the github README. It's for making grids only. For all the boundary condition remapping, I use pyroms (Python 2), trying to transition to pycnal (Python 3). But really, there's no reason for you to give up your ...

Re: Blow up problems for an Internal Tide case

Many of us have blowing up problems from time to time. However, most of us on this forum are not familiar with that dialect of ROMS cppdefs. Is this the CROCO code you are using?
