4. Synthesis

This test case makes it possible to validate the continuation of calculations by moving from Europlexus to*Code_Aster*, on a reinforced concrete building model. More precisely, we start by validating the rereading of fields at nodes or Gauss points to continue with an explicit calculation with DYNA_NON_LINE. Then, we validate this pursuit by switching to an implicit time schema.

The differences observed are satisfactory and consistent with the differences in modeling between the codes (mainly at the level of the mass matrix, which can be consistent or lumped). Post-treatments such as SRO calculated on data from ARCHIVAGE or OBSERVATION are also validated.
