The “Mun” iteration of Minsky, the Open Source system dynamics program with special features to handle monetary modeling, is now available at SourceForge:

The program now supports the basic features needed for system dynamics in general, and has the added capability of modeling financial flows using “Godley Tables”, which are based on the double-entry bookkeeping standards of accountants and make it easy to generate dynamic (ordinary differential) equations of financial flows.
