COCO simulator

It was originally intended as a test environment for CAPE-OPEN modeling tools but now provides free chemical process simulation for students.

It is an open flowsheet[1][2] modeling environment allowing anyone to add new unit operations[3] or thermodynamics packages.

COCO's thermodynamic library exports more than 100 property calculation methods with their analytical or numerical derivatives.

COCO includes a LITE version of COSMOtherm, an activity coefficient model based on Ab initio quantum chemistry methods.

COCO features a reaction numerics package to power its simple conversion, equilibrium, CSTR, Gibbs minimization and plug flow reactor models.
