BioChem

Free library for biochemical modeling and simulation with Modelica.

Library description

The design idea behind the BioChem library is to create a general purpose Modelica library for modeling, simulation and visualization of biological and biochemical systems. The classes implemented in the BioChem library describe substances and reactions that can take place in-between these substances in a diverse number of biochemical pathways.
