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.

4.4.3. notes#

The relative differences with the results of modeling A taken as a reference are generally quite small despite a difference of \(7.0\text{\%}\) in \(\mathit{DZ}\) at the moment \(1.0\) and of \(6.0\text{\%}\) in \(\mathit{DX}\) at the moment \(1.2\). We notice that the differences are decreasing over time and are finally small at the moment \(5.0\). The “GROT_GDEP” cutscene of the element POU_D_TGM is therefore very satisfactory.
