Figure 2. Example for the time step $i$ of the time-discrete approach to compute resulting collision force $\underset{¯}{F_C}$ and acceleration $\underset{¯}{a}$ for the deformable, moving object A and the fixed, not deformable object B (no EES model needed).

Figure 3. Comparison between predicted (below) and documented deformations (above) of the Audi Q7, projected from the 2 D substitute model to a 3 D EES model.
