Python Ocean Model 2.0 (pyOM2)
Contents
Introduction
pyOM2 is a numerical circulation ocean model powered by Python
Features are:
* Cartesian or pseudo-spherical coordinate systems
* Hydrostatic or non-hydrostatic configurations
* energetically consistent parameterisations
* Fortran and Python front end
* Graphical User Interface
* fully parallelized using MPI
Idealized and realistic configurations are simple and easy to configure and to integrate. A Fortran and a Python version are based on the identical Fortran90 code. Several idealized and realistics experiments and examples are preconfigured and can be easily chosen and modified using two alternative configuration methods based on Fortran90 or Python.
Resources
Source code as tar ball
- pyOM2 installed on lightweight Debian system as Virtual box client
Prerequisites and Installation
Prerequisites for the Fortran front are Fortran 90 compiler, Lapack and NetCDF library
Prerequisites for the Python front end is Python and the module Numpy, several other modules can be used to provide a graphical user interface, Netcdf IO, etc
For installation details refer to the Documentation
