Hello,
Is it possible to use XFEM without defining initial crack ?
In my model i dont have an initial crack, i would like to use xfem to predicts the crack initiation sites considering the applied boundary conditions. Is it possible ?
Thank you in advance for any help.

Greetings Kadred.
The simple answer is yes. In fact, XFEM allows one to use a "sane" mesh, without directly modeling the crack.

thanks for your answer.
If it possible, so what do i have to do in the step "DEFI_FISS":
"FISS=DEFI_FISS_XFEM(MAILLAGE=MAILLA,
TYPE_DISCONTINUITE = / 'FISSURE', [DEFAULT]
/ 'INTERFACE'
DEFI_FISS=_F()
)
"

Hello Kadred.
One suggestion is to look at test case SSLV315.

I took your advice and took a look at the SSLV315 document. but as I am a beginner on salome meca and that in SSLV315 there are not the steps to build the model I switched to the document forma01 where in the modelization D it is question of XFEM.
However, I have an error that I don't understand:
!----------------------------------------------------------------------------------------------------------------!
! <EXCEPTION> <CALCULEL_54> !
! !
! Le paramètre: PSTANO de l'option: INI_XFEM_ELNO n'est pas connu des TYPE_ELEM du LIGREL: modlxfem.MODELE !
! Champ : modlxfem.STNO !
!----------------------------------------------------------------------------------------------------------------!
Can you help me ?
the model is attached .

Hello kadred.
I am not sure about your question...are you trying to apply XFEM to a beam model?

no I worked on the modelization described in the document: V3.02.326. it is not a beam model.
The .hdf file is attached.
Thanks
