7. E modeling

7.1. Characteristics of modeling

This modeling is identical to modeling B.

7.2. Principle

A calculation is performed with DYNA_ISS_VARI by entering a different signal in each direction (operands ACCE_X, ACCE_Yet ACCE_Zde EXCIT_SOL). Three other calculations are then started for which only one sign is entered (ACCE_X, ACCE_Ypuis ACCE_Z). The results are reported on a physical basis. The results of the unidirectional calculations are then combined using CREA_CHAMP and CREA_RESU. The result created is the reference for the result with signals in all three directions.
