Laminar Flow with a high velocity.

I'm playing laminar flow module in a pipe. The problem is when I increase the inlet velocity to 0.5m/s, which is definitely too large for laminar flow, the software gives:
"Failed to find a solution.
Maximum number of Newton iterations reached.
Returned solution is not converged."
But if I low down the velocity, the module works well.
I wonder the laminar governing equation should have a solution no matter what inlet velocity is given. How does it happen? I know this is turbulent flow in fact.

Does the software calculate the Reynolds automatically? And use another governing equation?
