Computer Aided Grid Interface (CAGI) is a computer program that serves as an interface between computer-aided design/computer-aided manufacturing (CAD/CAM) programs and computational fluid dynamics (CFD) programs. CAGI reads Initial Graphics Exchange Specification (IGES) files from CAD/CAM programs and converts from CAD/CAM geometries to nonuniform rational B-splice (NURBS) surfaces to be manipulated or written out in forms appropriate for generation of grids for CFD.
