Cohesive contact not converging

user12
Hi,

I am trying to use cohesive surface elements to model delamination. Its two wedge type shapes between which i insert the cohesive elements. It work fine if i dont do the partition but if i run the same model with partitioning the part then i get the following warning and the solution didn't converge.

***WARNING: COHESIVE CONTACT RESPOSE IS COMPUTED AT SLAVE NODE 71219 INSTANCE
             NEWPART-SMA-1 THAT FELL OFF THE MASTER SIDE USING A SEPARATION OF
             1.00000E+36.

Does any one know what could be the issue ?

Thanks
