CAD data extraction for CFD simulation

Project reference: 1721

CAD geometry is a necessary input to run a numerical simulation. However, CAD geometry from the design office is not suitable for use directly in numerical simulation. This is due to CAD complexity with many small details such as fillets, small edges and faces. Simplification and extraction of the CAD data is necessary beforehand the numerical simulation. The simplification and extraction of the CAD data will be done in open source software Open CASCADE. The numerical simulation will beperformedwith an open source software such asOpenFOAM. The main goal is to prepare the geometry for the numerical simulation in programmatic way using the Open CASCADE. With this project, a complete method of CAD extraction, meshing and numerical analysis will be done in programmatic way. Python and C++ will be used as programming tools.
