- The command file defines > Problem characteristics > Physical models and parameters > Material properties > Equation solvers

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

build/import geometry create multi-block structures create patches mesh the geometry create a CFX-4 geo file

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
