what on earth does " nondefinite material, mesh 1 " mean?

Currently I'm trying to realize a pipe stress fatigue analysis by refering to the validation case rccm-15, and I have completed static analysis, spectral analysis and transient analysis. I use the POST_RCCM to combine the results obtained, the code edits as below:

TBRCCM11 = POST_RCCM(CARA_ELEM=CARA_POU,
                     CHAM_MATER=CHMAT1,
                     INDI_SIGM=_F(TOUT='OUI'),
                     MODELE=MODELE1,
                     OPTION='FATIGUE',
                     RESU_MECA=(_F(NOM_CHAM='EFGE_ELNO',
                                   NOM_CHAR='ETAT 1 SITUATION 3',
                                   NUME_CHAR=1,
                                   RESULTAT=RMECA121,
                                   TOUT_ORDRE='OUI'),
                                _F(NOM_CHAM='EFGE_ELNO',
                                   NOM_CHAR='ETAT 2 SITUATION 3',
                                   NUME_CHAR=2,
                                   RESULTAT=RMECA122,
                                   TOUT_ORDRE='OUI')),
                     RESU_THER=_F(GROUP_MA=('PT16R', 'P2'),
                                  NUME_RESU_THER=200,
                                  TABL_MOYE_THER=TABMOP2,
                                  TABL_RESU_THER=TABTHP2),
                     SITUATION=_F(CHAR_ETAT_A=(1, ),
                                  CHAR_ETAT_B=(2, ),
                                  NB_OCCUR=15000,
                                  NOM_SITU='SITUATION 1',
                                  NUME_GROUPE=1,
                                  NUME_RESU_THER=(200, ),
                                  NUME_SITU=1,
                                  PRES_A=15500000.0,
                                  PRES_B=15500000.0,
                                  TEMP_REF_A=75.0,
                                  TEMP_REF_B=75.0),
                     TYPE_RESU='DETAILS',
                     TYPE_RESU_MECA='B3600',
                     ZONE_ANALYSE=_F(GROUP_MA=('P2', )))

but codeaster always give the same error information, which I cannot understand, could anyone read it? thanks for help!
the error message is as followed:

<S> Exception user raised but not interceptee.
The bases are fermees.                        
Type of the exception: error                  
                                              
 nondefinite material, mesh  1    

I upload  the astk files below.
Merci de m'en débarrasser!
