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.

For more than 15 years CastNet has been supporting CFD users with an outstanding OpenFOAM case setup and monitoring:

• GUI-environment: Establishment of a complete GUI based environment including pre-processing (meshing, case setup), solution monitoring and post-processing. By this: Access to strong open source solver capabilities without editing text files or need to know OpenFOAM®’s keyword structure in detail.
• CAD based meshing: Provision of access to reliable, stable and high quality CFD and FEA meshing based on CAD kernel geometry.
• Cross-platform usage: Support for a flexible environment for OpenFOAM® on Windows and Linux operating systems (local, server, cloud). Exported cases are cross-platform and can be easily moved from one operating system to the other.
• Time effective: Reduction of the time from CAD model to run-ready case in comparison to the direct usage of open source solver technology.
• Simplified multi-purpose usage: Easy case setup for more than 30 OpenFOAM® solvers by the delivered comprehensive template library.
• Reliable simulations: More safety regarding the simulation results by a reliable and stable CFD/FEA analysis with detailed job and convergence control (runGui).
• Compatibility: Always up-to-date and compatible to current OpenFOAM® versions provided by OpenFOAM foundation, ESI and BlueCape (Windows).
• Coupling and FSI: Extending the solution capabilities by coupled CFD/FEA analysis for thermal stresses and mechanical Fluid-Structure Interactions (FSI) with preCICE.
