8. Summary of results

This test case makes it possible to validate the command DYNA_ISS_VARI by calculating the response of a rigid superficial foundation represented either by rigid body modes (MODE_INTERF =” CORP_RIGI “), or by any modes on spring mats determined from static ground impedances (MODE_INTERF =” QUELCONQUE”). The results obtained with DYNA_ISS_VARI are in good agreement with the results of the Mita and Luco reference.
