Ahmed, do what I did above. Use vector instead of contour.

Opaque, what you assumed to be wall is actually just an interface in the flow field (see my vector plot above). So its blue coloring in...

Yes, Thomas, that's what I thought to. I plotted velocity, of course, as you can see from the image at the top. The magnitude of velocity in the domain during negative flow is obviously not 0, as you...

Oscillating flow: wrong results when flow is negative

This is a minimal transient test case for an oscillating flow. The geometry is 1/6 of a tube with appropriate symmetry planes. The inlet velocity is specified by a data profile (with t and r...
