Hello everyone,

I've noticed that changing the position of zero pressure in the fvSolutions dictionary of the simple rotor tutorial changes the flow field. The first two images show the flow field at t = 0.0125 s with default fvSolutions settings, where the reference pressure is set to zero in the lower left corner. Notice how there seems to be a flow source in that corner? This shouldn't happen with incompressible flow.

Changing the location of the reference pressure to the lower middle of the domain also moves the flow source. This is shown in the next pair of images. This issue also occurs in the twoSimpleRotors tutorial.

Can anyone shed some light on why this happens? Is this a bug?
