Our modelling environment CastNet offers a cost-efficient and comprehensive support for the open source CFD toolbox OpenFOAM® and for the finite element solver CalculiX.

One major goal is to avoid restrictions to OpenFOAM®’s functional range and to keep compatibility between OpenFOAM® releases. As a result, the user may switch between text file and GUI based case setup at any point of time. Furthermore, the user can extend CastNet’s support for self-developed solvers as well.

In combining the analysis programmes, customers find a complete simulation environment that conforms to industrial standards at a fraction of the usual costs for software licensing. This is possible due to the customisation and combination of different tools which are adapted to open source software.

The outstanding features of the CastNet modelling environment are:
