A HYbrid coordinate Parallel Ocean Program (HYPOP)
HYPOP
HYPOP is an ocean circulation model that is a hybrid in several ways, primarily
in the vertical coordinate. The momentum equations continue to be solved on
z-coordinates (depth as vertical coordinate), where the boundary conditions and
pressure gradient are less problematic. For the tracer equations, HYPOP utilizes
an Arbitrary Lagrangian Eulerian (ALE) scheme for the vertical coordinate. In
an ALE scheme, the vertical coordinate moves in a Lagrangian way and a periodic
remapping step allows the simulation to move to any (well, almost any) arbitrary
vertical coordinate. Such a scheme allows the model to utilize depth as the
vertical coordinate in the mixed layer while using a more Lagrangian
(e.g. isopycnal) coordinate in the deep ocean.
Other algorithmic improvements (over the POP model) are also expected in this
model, including a new remapping advection scheme and more advanced time-stepping
schemes. Most other software aspects of HYPOP will follow POP styles for
performance and portability.
Documentation
The entire model is one big undocumented feature. We do have internal documents
describing the methods used, but are not willing to share them with the world
at this point in time. Thank you for your interest.

Hey, we're still working on the model. You can't have it yet.
Release Notes
No release. No notes. End of story.
Bugs
No known bugs. Nor are any anticipated in the future.
Future Plans
We recently came up with a new scheme that should enable us to
bring this model up to a robust, working code much faster. But
I am afraid you will still need to wait for a bit.
