A method for presenting a graphic user interface (GUI) facilitating generation of selected ones of a Euler grid and a Navier-Stokes grid from a single set of predetermined parameters includes step for defining the geometry of a vehicle to be tested, defining the environment in which the vehicle is to tested, generating the selected ones of the Euler grid and the Navier-Stokes grid responsive the set of predetermined parameters generated in two defining steps, and post-processing the output of the generating step. Computer readable instructions for permitting a general purpose computer to instantiate a graphic user interface (GUI) generating selected ones of a Euler grid and a Navier-Stokes grid from a single set of predetermined parameters and a storage medium storing the computer readable instructions are also described.
