| 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)
Contents
Introduction
pyOM2 is a simple and easy to use numerical circulation ocean model to configure and to integrate idealized and realistic configurations.
Features are:
* Cartesian or pseudo-spherical coordinate systems
* Non-hydrostatic configurations
* several energetically consistent parameterisations
* Fortran and Python front end
* Graphical User Interface
Fortran and Python version are based on the identical Fortran90 code which is fully parallelized based on the MPI-library to enhance performance.
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
Sample Configurations
Several idealized experiments and examples are preconfigured and can be easily chosen and modified using two alternative configuration methods based on Fortran90 or Python.
Here is an example of a vertical shear instability in a 2D non-hydrostatic configuration using the Graphical User Interface
Realistic Configurations
