Problem with Coupled Solver!
 

I am trying to use a coupled solver for simulation with high order velocities using Fluent.

I am trying to use the converged solution for the lower velocity and chaging it to coupled and a step by step change in velocity to the higher one.

The residulas suddenly shoot up to a very high value. (Especially the energy equation and continuity equation curves)

Has anyone used a couple solver and experienced similar behaviour with Fluent.

What is the Mach number of your flow ? .

It is around 0.6.
