| pyOM2.0 (Python Ocean Model) is a numerical circulation ocean model which was written for educational purpose. It is meant to be a simple and easy to use numerical tool to configure and to integrate idealized and realistic numerical simulations of the ocean in Boussinesq approximation. Non-hydrostatic situations as well as large-scale oceanic flows can be considered, Cartesian or pseudo-spherical coordinate systems can be used. Several idealized experiments and examples are preconfigured and can be easily chosen and modified using two alternative configuration methods based on Fortran90 or Python. Prerequisites for the installation is a Fortran 90 compiler and the Lapack library, and for the Fortran front the NetCDF-library (since IO is realized mainly using the NetCDF format). For the Python front end, the numerical module \verb+numpy+ is required and several other modules can be used in addition, e.g. to provide a graphical user interface. Both version are based on identical Fortran90 code which is fully parallelized based on the MPI-library to enhance performance. |

Python Ocean Model 2.0 (pyOM2)
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. Fortran and a Python version are based on the identical Fortran90 core code. Several idealized and realistic examples are preconfigured and can be easily chosen and modified using two alternative configuration methods based on Fortran90 or Python.
