v5.06.110 PLEXU06 — Code_Aster chaining validation - Europlexus

Summary:

The purpose of this test is to validate the chaining of a non-linear transient calculation where the first part of the resolution is carried out by Europlexus via the CALC_EUROPLEXUS command, then continues in Code_Aster with the use of the DYNA_NON_LINE operator, with an explicit to implicit rebalancing step performed by the command MACRO_BASCULE_SCHEMA..

More specifically, the model implemented includes the following specificities:

• beam-type finite elements (POU_D_E),

• Q4GG type finite elements on triangular or quadrangular meshes,

• ground spring mats to model the ground under the foundation,

• loading of pressure type variable in time,

• linear zone,

• non-linear zone with behavior law GLRC_DAMAGE.
