That's not a rectangular channel. A rectangular channel has four no-slip walls. Symmetry boundary conditions are not physical in LES because of the kinematic...

DES and hybrid RANS/LES still behave mostly likely LES. You're only applying RANS in the viscous regions (where turbulence plays a less important role). I think your roughnesses are small. But you...

The only difference between a concrete channel and plastic channel is the wall roughness. You never need to specify what the wall material. The fluid does not care what the material of the wall is...

It's right next to the calculate button in the GUI. Or you can look up the TUI command if you don't have a GUI. Did you add perturbations to your flow? Go to...

This will create new variables for the time-averaged quantities and you will be able to get time-averaged wall shear from that.
