This site presents software tools that are used to create and numerically solve mathematical models.

Some Background

The challenge is to accurately and quickly calculate the solution to families of algebraic and differential equations. Some very bright folks at Linkoping University, Sweden have solved this problem and distribute their solution as the numerical methods environment named OpenModelica (

The software tools presented on the present site were created to work with and enhance the value of the Open Modelica environment.
