2. Benchmark solution#

2.1. 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.

All the components of significant EFGE_ELNO and SIEF_ELNO (greater than 1.0E-06) are compared in several nodes.

No uncertainty.
