Operator LIRE_PLEXUS
1 Goal
To see the file of results to format IDEAS produced by software EUROPLEXUS.
Allows to recover a transitory field of fluid pressure in a piping calculated using one
telegraphic hydrodynamic model (plane waves) of PLEXUS. The constant field of pressure definite by
element in calculation EUROPLEXUS is projected on a mechanical mesh agent of
Code_Aster using the elements hulls (DKT or COQUE_3D) and/or PIPE.
Product a concept of the evol_char type.

4 Examples
4.1
Example: reading of a mesh EUROPLEXUS
One reads on universal file IDEAS (logical unit 19) the telegraphic hydrodynamic mesh of
EUROPLEXUS and one transform it with the format of Code_Aster written on the unit 22. Mesh
EUROPLEXUS with the format of Code_Aster then is read again and placed in the concept of the type
mesh.
PRE_IDEAS (UNITE_IDEAS=19, UNITE_MAILLAGE=22)
mplexus = LIRE_MAILLAGE (UNITE=22,)
4.2
Example: creation of a result of the type “evol_char”
One reads on universal file IDEAS the fluid field of pressure function of time. This field, definite
on the telegraphic hydrodynamic mesh of EUROPLEXUS (with the format of Code_Aster), is then
projected on the mechanical mesh of Code_Aster for every moment of definition.
presplex = LIRE_PLEXUS (UNIT
= 19,

MAIL_PLEXUS

MESH

MODEL

TOUT_ORDRE =

)
4.3
Example: use of the result of the type “evol_char”
The concept “evol_char” previously definite is used under key word PRES_CALCULEE for
to manufacture a loading.
tank = AFFE_CHAR_MECA (MODEL = modaster,
…
PRES_CALCULEE
= presplex,
)
Other examples of use of operator LIRE_PLEXUS can be consulted in the files
controls of the case-test ZZZZ112, modelings A, B, C [V1.01.112].
