Velocity Source Not Working
 

Hello, i am new to OF, and I have been able to run all the examples, but I am having a problem getting any dynamics out of a case I have created where I have a 2D closed domain and a
momentumSource
{
type meanVelocityForce;

selectionMode all;

fields (U);
Ubar (10.0 0 0);
}

I am getting residuals = 0 for all times and no movement. My thinking is that this should simulate a surface stress.

My other files are as follows:
