Summary (AI generated)

The results from the RAM show the crash of the front bumper, which is accurate. This is a convergence study analysis. A RAM with a dimension of 20 would not be sufficient, but a RAM with a dimension of 100 would accurately reproduce the main features of the structure's response.
