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. |

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.
