View the resulting pressure and velocity fields as before. This time we also have a theoretical prediction for the velocity field we can check.

Select Filters, Data Analysis, Plot Over Line. Drag the two end points around, or click “P” to place them where the mouse pointer is. Make sure both values of $z$ is between $0$ and $0.01$, e.g. $0.005$. Click Apply. The velocity field should be linear in the steady state.
