Re: Singularity error

xfem = DEFI_FISS_XFEM(identifier='13:1',
                      CHAM_DISCONTINUITE='DEPL',
                      DEFI_FISS=_F(GROUP_MA_FISS=('Curve_1', ),
                                   GROUP_MA_FOND=('Curve_1', )),
                      MAILLAGE=mesh)

is, GROUP_MA_FISS=('Curve_1', )  the same of GROUP_MA_FOND=('Curve_1', ) ????

asking better
Curve_1, is the same entity in both camps ???
