Abstract: As a set of specific CAD analysis tool for two-dimentional axisymmetric transonicnozzle flow simulation, the CFD/Nozzle software contains a highly integrated operation environmentthat can join the procedure of code preparation, grid generation, numerical computation and graphoutput together to form an interrelated unity. Operation environment can also provide detail helpinformation that include colorful diagram and documents. The source cede of computer program iseditable, and can be compiled or linked automatically. Present in the paper is the CFD/Nozzle softwaredesign consideration, related technical route and some results of its application.
