Extract boundary layer values with Tecplot

PyTecplot vs. Macros: efficiency, efficiency, efficiency

With Tecplot you can use iso-surfaces to estimate boundary layer thickness, but what if you want to plot a field variable against the distance from a wall? The procedure involves finding the normal, calculating distances along it, extracting the variable at these distances, then creating a plot. Python is much more efficient than a macro for such computations, as discussed here.
