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.

Features are:

* Cartesian or pseudo-spherical coordinate systems

* Non-hydrostatic configurations

* several energetically consistent parameterisations

* Fortran and Python front end

* Graphical User Interface

Python Ocean Model 2.0 (pyOM2)

Introduction

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.

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

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

Installation

For installation details look at 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
