Shear rate around cylinder (radial shear rate), Navier Stokes

bborer
I'm trying to calculate the radial shear rate around a cylinder in laminar flow.

COMSOL stores the shear rate spf.sr directly when solving the NS equation (e.g. https://www.comsol.com/forum/thread/83661/wall-shear-stress).

Does FEATool store something similar in the background or is there an easy way to calculate it based on the grid and velocity field?

Thanks!
Ben
