An arc-length technique is used to obtain the response of the structure, the calculation times cannot therefore be directly imposed. However, an effort is made to choose the values of the control state that are closest to the reference times.

8.4.3. notes#
The relative differences with the results of modeling A taken as a reference are generally quite small despite a difference of \(9.0\text{\%}\) in \(\mathit{DZ}\) at the moment \(1.0\) and of \(6.0\text{\%}\) in \(\mathit{DX}\) at the moment \(1.2\). We then notice that the differences decrease to values of the order of \(0.5\text{\%}\) and then go up for the effort values \(3.0\), \(4.0\) and \(5.0\) up to a maximum of \(3.5\text{\%}\). The “GROT_GDEP” kinematic of the element POU_D_EM is therefore satisfactory.
