9. Summary of results

The precision on the movement, speed and acceleration of node \({x}_{2}\) at time \(t=\mathrm{80 }s\) is excellent (relative error \(\text{< 1\%}\)).

This test therefore validates the operators for calculating the linear transient response on a modal basis calculated by dynamic substructuring (with and without damping), as well as the integration scheme with 2nd order adaptive time steps of the transient calculation operator on a modal basis.
