Abstract: Disclosed is a method for evaluating computational fluid dynamic simulation results. The method includes: performing at least two baseline runs of a simulated area or volume containing a first vehicle body shape using a set of initial conditions, performing a change run using a second vehicle body using the set of initial conditions, creating a noise map based on differences between the second baseline run and the first baseline run, creating a change map based on differences between the change run and a selected baseline run, and comparing the change map to the noise map.

Abstract: Disclosed is a method for evaluating computational fluid dynamic simulation results. The method includes, based on a set of initial conditions, performing a first baseline run and a second baseline run of a simulated area or volume containing a vehicle body shape, and then performing a change run of the simulated area or volume containing a modified vehicle body shape, and performing the following actions within the simulated area or volume: plotting an iso line of the first baseline run and a corresponding iso line of the second baseline run, plotting an iso line of the change run that corresponds to the iso line of the two baseline runs, and comparing whether the iso line of the change run falls between the iso lines of the two basline runs. If not, then the modification to the vehicle body shape may be considered significant.

Abstract: A method of installing a vehicle component to a vehicle panel is provided. The method includes aligning a rib receiving channel of the vehicle component with an alignment rib that is formed integrally with the vehicle panel while also aligning a fastening opening of the vehicle component with a fastening opening through the vehicle panel. The alignment rib is inserted into the rib receiving channel. A fastener is inserted through the fastening openings of the vehicle component and the vehicle panel. The fastener is tightened while the alignment rib and rib receiving channel inhibit rotation of the vehicle component.
