Steps in Model Creation - build wireframe using points, curves, surfaces and solids. - define constraints for solids with area mismatch. - define boundary conditions (inlet, outlet, walls). - mesh all surfaces
AEATECHNOLOGY ENGINEERING SOFTWARE Performing a CFD Analysis Define the problem Geometry Domain in which the governing equations will be solved and solutions obtained
The geometry is a set of hexahedral solids which have a logical representation. Each block in the geometry is called a ‘solid’. Each solid in the geometry can represent a fluid, porous or solid region
Simplify the problem - Simplify geometry > Ignore features that do not affect the flow > Use as many blocks as possible to set the geometry > Make blocks meet at complete faces
