| 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. |
