CAD model based input

A single graphical user interface for CFD and FEA case setup

• Definition of mesh specifications and solver settings (e.g. velocity inlet conditions) with associations to the CAD geometry
• Storage of the complete case definition in a single data-file
• Combined analysis (e.g. thermal stresses estimation in CalculiX based on OpenFOAM® CHT data) can be conducted based on a single CAD input.
• Easy modification of settings for meshing or target solver with only a few clicks

CastNet allows a high quality geometry import based on CAD kernel data. There is no need to repair the CAD geometry, and volume information is preserved.

The CAD import includes:

• Direct access to Parasolid, ACIS and Granite (Pro-E) parts and assemblies
• Internal generation of a non-manifold model of complex assemblies resulting in conformal grids between the various regions (parts)

This feature

• simplifies the case setup for CFD region models, e.g. Porous, MRF, AMI rotating, CHT.
• enables the user to easily combine different mesh topology regions, e.g. free mesh regions with extrude meshes.
• For FEA applications, assemblies with a manifold geometry representation can be used.
• Automated geometry improvement for meshing by suppression of sliver faces if needed
• Flexible usage including model exchange between Windows and Linux operation systems.
• Fast, reliable and error-free case setup for meshing and solver settings by predefined templates.
