The equation for strain rate given in PIVLab is ∂u/∂x - ∂v/∂y and is referred to in the paper "Stamhuis, E. J. (2006), Aquatic Ecology, 40(4), pp. 463–479.". However, this equation seems inconsistent …

Hi,
Many thanks for implementing Free stream boundary condition #138. It works nicely on scalar fields. But how to use it on the velocity field?
I am willing to set up the velocity field and apply a…

In chapter 18 on page 473 in several places it says "laminar" flow when it surely should have said _steady_ flow.
For example, in a low-Reynolds-number situation, a piston pump produces a non-steady …
