Full evaluation of a design concept requires the definition of many complex details. However, complex geometric details constrain design flexibility. Think of the value of a complex model defined in a way that both details and basic design elements can be changed in seconds. The new suite of parametric free-form surface and solid shape parameters in the 2020 release of Inspire Studio make it possible to explore and analyze broad ranges of a design space. The presentation was part of the ATCx CFD 2020, presented by Paul Stewart, VP, Automotive Aerodynamics Modeling and Visualization at Altair
