MicroSim
MicroSim is a micro-economic modelling program designed to complement SimX (which is a macro-economic modelling system). Like SimX, it provides its own graphics, but it can also output its results in the form of a CSV file which can be read into a spreadsheet for further analysis or formatting.
Technicalities
MicroSim has been developed using Qt (5.9) and uses Qt Frameworks throughout. The files in this repository include the .pro file so it can easily be cloned as a Qt project in Qt Creator. It is being developed, so far, under Mac OSX, but it should be straightforward to recompile it on any platform supported by Qt.
