v1.01.394 ZZZZ394 — PRE_EPSI check

Summary:

This test has no physical meaning, it is essentially a computer test.

It aims to validate the PRE_EPSI load of AFFE_CHAR_MECA for 3 types of possible assignments:

• by direct assignment under the PRE_EPSI keyword (via EPXX, EPYY,…)

• by creating a map via CREA_CHAMP, taken into account via the EPSI keyword from PRE_ESPI

• by providing a deformation field from another calculation (also via EPSI)

The principle is as follows: a loading PRE_EPSI is applied to a mesh in which only rigid body movements are blocked. The deformation field is then calculated (EPSI_ELGA or DEGE_ELGA) and it is verified that the values are indeed those that were provided (for several components and several Gauss points).

Modeling A:

A DKT element. Assignment by a map and by a field to Gauss points

Modeling B:

A DKTG element. Direct assignment

Modeling C :

A 3D element. Assignment by a field to Gauss points
