5. example

The main commands used to perform a transient non‑linear thermal calculation are defined below. The example shows how to continue the calculation by enriching the result concept and how to specify the « initial » field.

lr8 = DEFI_LIST_REEL (...)


conduit = DEFI_FONCTION (NOM_PARA = 'TEMP',

VALE =… )

enthal = DEFI_FONCTION (NOM_PARA = “TEMP”,

VALE =…)

aluminum = DEFI_MATERIAU (THER_NL =_F (LAMBDA = duct,

BETA = enthal))

…

temple = THER_NON_LINE (MODELE =moth, CHAM_MATER =chmat,

ETAT_INIT =_F (VALE = 20.0), INCREMENT =_F (LIST_INST = lr8, NUME_FIN = 20), EXCIT =_F (CHARGE = chth), CONVERGENCE =_F (RESI_GLOB_RELA = 1.E-8, ITER_GLOB_MAXI = 20), )

…

temple = THER_NON_LINE (reuse = temple,

MODELE =moth, CHAM_MATER =chmat, ETAT_INIT =_F (EVOL_THER = temple, NUME_ORDRE = 20), INCREMENT =_F (LIST_INST = lr8), EXCIT =_F (CHARGE = chth), CONVERGENCE =_F (RESI_GLOB_RELA = 1.E-6, ITER_GLOB_MAXI = 10), )
