Abstract: A computer-implemented method for vehicle impact analysis including obtaining a B-Rep representing an outer surface of a vehicle, the B-Rep having faces and obtaining a radius value for a contact sphere. The method also includes determining one or more two-point-contact curves of the B-Rep for the radius value. The determining includes, for each respective pair of portions of a plurality of pairs of portions of the B-Rep, applying a respective two-point-contact-curve computing algorithm. The computing algorithm is based on the respective pair of portions. The computing algorithm is parallelized over the plurality of pairs of portions. The method forms an improved solution for vehicle impact analysis.
