Sigularity error in comsol 5.6

Please login with a confirmed email address before reporting spam

Hi! I am trying to solve two coupled PDE for optical soliton.I have tried different initial and boundary conditions but each time this error is occuring: Repeated error test failures. May have reached a singularity. Time: 3.1808107947292128 s. Last time step is not converged. How can I fix this error? Thanks in advance.
