Hello!

I simulated a flow around surface-mounted cube according to the experiment of Martinuzzi and Tropea. I use a simpleFoam solver and had a results of filed of velocities and pressure very close to the real.
But when I plot a residuals I saw that it is very hight.


How can I control it? I want to have residuals about 1e-05.

I could be mistaken, but isn't this an unsteady problem? That could be why your residuals aren't behaving.

jferrari, maybe I have a mistake, but I try to get a steady solution. I use a simpleFoam - in user's gid it is a steady solver
