Welcome to the Assimulo project Trac

Assimulo is a Python based simulation package for solving explicit ordinary differential equations (ODEs) and implicit ordinary differential equations (DAEs). Special attention has been given to the SUNDIALS (​https://computation.llnl.gov/casc/sundials/main.html) solvers IDA(s) and CVode(s). For more information, please visit ​http://www.jmodelica.org/assimulo or our forum ​http://www.jmodelica.org/forums/jmodelicaorg-users/assimulo

For download, the latest release of Assimulo can be found on PYPI: ​http://pypi.python.org/pypi/Assimulo
