Abstract:
A system for designing an automotive vehicle by enabling dynamic placement of particle injection points into a flow domain to permit visual observation and alteration of resulting particle trajectories under a computed flow solution over a computer aided design (CAD) model representative of a desired portion of the vehicle represented on a display means by a computer having memory means, processor means and user input means associated therewith, the system comprising:particle injector placement code means, including stone injector code means for simulating ejection of particles from a predetermined tire patch of a tire of the CAD vehicle, operable with the user input means to dynamically effect a desired placement of at least one particle injector on the display means with respect to the desired portion of the CAD model;trajectory determination code means for computing at least one trajectory for a particle stream emanating from at least one particle injector relative to the desired portion of the CAD model for a predetermined set of particle characteristics in a predetermined set of particle external conditions; andtrajectory display code means for effecting display of the at least one trajectory with respect to the desired portion of the CAD model.
