Benchmark solution ===================== Calculation method used for the reference solution -------------------------------------------------------- Several methods are used: • The coordinate system for the structural elements is known, so the change in coordinate system can be calculated using the transition matrix. • In command MODI_REPÈRE we ask to calculate the EFGE_ELNO in the coordinate system of the structural elements. So EFGE_ELNO should not be changed. We compare the EFGE_ELNO before and after the MODI_REPERE command. • In command MODI_REPÈRE we ask to calculate the SIEF_ELNO in the coordinate system of the structural elements. So SIEF_ELNO should not be changed. We compare the SIEF_ELNO before and after the MODI_REPERE command. • After the EFGE_ELNO change in the global frame of reference and in some cases, they correspond to REAC_NODA or FORC_NODA. In these cases the comparison is made with these fields. Benchmark results ---------------------- All the components of significant EFGE_ELNO and SIEF_ELNO (greater than 1.0E-06) are compared in several nodes. Uncertainties about the solution ---------------------------- No uncertainty.
