Dear all,
I am trying to solve a simple model with Comsol to find the
pressure drop in a rectangular channel W=5mm, h=0.6mm, L=10mm. When i try to set the inlet velocity to 0.5m/s the solver shows the error message "Maximum number of newton iterations reached". The solver works fine if i set the input velocity to lower velocity(eg., 0.005m/s). when i increase the velocity to 0.05 m/s the solver ends up with the error message. I even tried to increase the height of the channel, still get the same error sequence.
I am using a Stationary, Direct (Pardiso)solver.
Any comments or help is much appreciated.
Thanks in advance
Arun
