open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello, everyone,
I am running a t2d-sisyphe internally coupled simulation in telemac v6p3.
The continued computation in t2d runs without problems, but if I want to run a continued computation coupled with sisyphe a couple of problems arise.The error is:

ERROR IN INIT-MIXTE:
THE SUM OF THICKNESS OF BED LAYERS IS DIFFERENT FROM ERODIBLE BED THICKNESS

I have look the code in init-mixte.f,
DO I=1,NPOIN
ELAY(I)=ZF(I)-ZR(I)
EST=0.D0
! IF(NOMBLAY.GT.1) THEN
DO J=1,NOMBLAY
EST=EST+ES(I,J)
ENDDO
! ELSE
! EST=ES(I,1)
! ENDIF
DIFF= ELAY(I) - EST
IF(ABS(DIFF).GE.1.D-4) THEN
WRITE(LU,*) 'ERROR IN INIT-MIXTE:'
WRITE(LU,*) 'THE SUM OF THICKNESS OF BED LAYERS
* IS DIFFERENT FROM ERODIBLE BED THICKNESS'
CALL PLANTE(1)
STOP
ELSE
ES(I,NOMBLAY) = MAX(ES(I,NOMBLAY)+ DIFF,0.D0)
ENDIF
ENDDO

I think, the ZF is the ELEVATION OF BOTTOM, it is BOTTOM in the result file? ES is the thickness of seabed? I have no NON ERODABLE BED.

What is the problem?
