Simulation Not Converge

Hello, I'm quite new in COMSOL, and I want to ask something about simulation not converge.
So, now I am modelling a venturimeter effect in pulsatile flow. When I try to simulate my model with relative tolerance in 0.05 or smaller I always got this message:
Repeated error test failures. May have reached a singularity. Time : 0 Last time step is not converged.
But when I make my relative tolerance higher than 0.05, my simulation works and have a fine result.
Is there something I can try to revise if I want to my simulation work but with relative tolerance smaller than 0.05?
