4. Summary of results

This test case shows the good functioning of modeling the behavior of beams using a multi-fiber approach. A loop, created with the Python language, makes it possible to retrieve information at different time steps.

• The calculation of the stiffness matrix, option RIGI_MECA, is based on a AFFE_CHAR_MECA_F.

• The calculation of the vector of internal forces is carried out by a CREA_CHAMPà from a STAT_NON_LINEen recovering the SIEF_ELGA.
