How to find shear stress in COMSOL 4.2

Hello,
I am trying to generate a line plot of shear stress in Comsol 4.2. In the older version I was able to do this by setting tau= eta*(uy+vx) in the post processing plot parameters>line plot equation. Is there a similar way to accomplish this task in the newer version? I would appreciate any help.

Hi
nothing has really changed between 3.5 and 4 w.r.t. lower level fem methodology, at least not I see it. so all "physical" formulas valid in 3.5 remain in v4. With the important exception that you must adapt to the new variable names.
And in solid the default spatial frame on makes a distinction between upper and lower case coordinate variables x,y,z and X,Y,Z
And in V4 you have far more predefined variables, probably yours is already defined, turn on the "equation" node and take a look under the hood ;)

Good luck
