Hi
I need to define an expression for calculating scalar shear stress on a rotating impeller.
I have to specify all six component of the stress tensor in this expression.
but I can specify 3 component ,I mean wall shear X,Y and Z.
how can i define zx,zy and xy component?
thanks for any response.

ghorrocks is just really niceghorrocks is just really niceghorrocks is just really niceghorrocks is just really nice
The usual definition is the sigma(xx)/(yy)/(zz) are the normal stresses and these are calculated from the pressure. The cross terms sigma(xy) are the tangential stresses which are from the wall shear stress.
