But === Read the results file in IDEAS format produced by the EUROPLEXUS software. Allows you to recover a transient fluid pressure field in a pipe calculated using a wire hydrodynamic model (plane waves) from PLEXUS. The pressure field defined as constant per element in calculation EUROPLEXUS is projected onto a corresponding mechanical mesh of *Code_Aster* using shell elements (DKT or COQUE_3D) and/or TUYAU. Produces an evol_char concept.
