Claim 0:
1. A method for evaluating computational fluid dynamic and computer aided engineering simulation results, the method comprising:
with a processor comprising a memory:
providing a first vehicle body shape to be simulated;
providing a set of initial conditions;
performing a first baseline computational fluid dynamic simulation and a second baseline computational fluid dynamic simulation of a simulated area or volume containing the first vehicle body shape using the set of initial conditions;
performing a change computational fluid dynamic simulation using a second vehicle body using the set of initial conditions;
for each point within the simulated area or volume:
creating a noise subtraction image by numerically subtracting a second scalar field of the second baseline computational fluid dynamic simulation from a first scalar field of the first baseline computational fluid dynamic simulation;
creating a change subtraction image based by numerically subtracting a third scalar field of the change computational fluid dynamic simulation from a scalar field of a selected baseline computational fluid dynamic simulation selected from the first baseline computational fluid dynamic simulation or the second baseline computational fluid dynamic simulation; and
comparing the change subtraction image to the noise subtraction image.
