CastNet simplifies the usage of CAE solution technologies for open-source solvers: Beside typical text file editing an alternative GUI based way to work with OpenFOAM®  is provided,  while still maintaining the full compatibility with standard OpenFOAM® releases. As a result a flexible workflow is established and the user may switch between text file and GUI based case setup at any point of time.

The combination of the powerful open-source solver technology with DHCAE’s professional GUIs for case set-up, meshing and monitoring tools results in complete CAE environment that conforms to industrial standards of high-end simulation tools at a fraction of the usual costs for software licensing.

The outstanding features of the CastNet modeling environment are:
