Efficient CFD Processes Through Abstract Modeling

Model – Contains all information relevant for a CFD simulation like mesh specifications, volume and boundary conditions, initial conditions, needed solver output, etc. Simulation set-ups are defined through classes, relations and attributes in an object oriented approach avoiding issues encountered with history based strategies. Abstract Models are shape and CAD system independent but CFD solver specific. Simulation Model – Automatically created by FluidConnection through the “synchronization” of an Abstract Model with a CAD Model, CFD View. The parameters contained in the Abstract Model are applied to the targeted geometric entities. Mesh Model – Automatically created by FluidConnection applying the mesh parameters contained in the Abstract Model to the CAD Model, CFD View. The internal format of a Mesh Model as well as the mesh strategy depends on the CFD solver for which the mesh is generated. Solver Input Files – Automatically created by FluidConnection applying the information contained in the Simulation Model for the solver specified in the Abstract Model. Capabilities • Automation of CFD Simulation Process: FluidConnection is ideally suited to implement efficient, highly automated and reliable Simulation Based Design processes for CFD. The reliability comes from two key factors: re-usable data templates (or abstract models) for the simulation set-up and exploitation of the CAD system for all geometry manipulations. • Geometry Independent Abstract Models: All CFD simulation settings are defined in geometry independent abstract models. Abstract models apply object oriented principles, which makes them re-usable while conserving valuable simulation know-how. • Automatic Creation of CFD 3D Meshes: FluidConnection features comprehensive automatic mesh generation capabilities for surface, volume and boundary layer meshes. Different mesh strategies allow the creation of meshes optimized for finite volume and finite element based solvers. All necessary geometry Interrogations are done through the CAD system, thereby avoiding any geometry translation problems. • Automatic Creation of CFD Solver Input: Shape independent abstract models containing all Information to perform a CFD simulation in combination with a specific CAD model are all that is needed to automatically create mesh and CFD solver input files. • Fully Automatic Production Mode: FluidConnection’s production mode allows any person involved in the development process to initiate CFD simulations creating quality results. A user, e.g. a CAD designer only selects a CAD model and an appropriate abstract model to automatically create the CFD mesh and solver input files.
