A computer-implemented method for vehicle impact analysis comprises providing (S10) a B-Rep representing an outer surface of a vehicle, the B-Rep having faces; providing (S20) a radius value for a contact sphere; and further determining (S30) one or more two-point- contact curves of the B-Rep for the radius value. The determining (S30) includes, for each respective pair of portions of a plurality of pairs of portions of the B-Rep, 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.
