But if you still want to use INCLUDE_MATERIAU, this keyword should be in your main comm file, pointing to external file (material library). That file should contain only material definitions, for example:
Steel=DEFI_MATERIAU(ELAS=F(E=210000.0,
NU=0.3,),)
Alu=DEFI_MATERIAU(ELAS=F(E=70000.0,
NU=0.33,),)
In your main comm file you should have:
INCLUDE_MATERIAU(FICHIER='path_to_your_material_lib_file/materials.comm')
and then "invoke" one or more of the materials and assign it by (in this case steel applied to everything):
MatField=AFFE_MATERIAU(MAILLAGE=Mesh,
AFFE=(
_F(TOUT='OUI', MATER=Steel,),
)
)
