Dear buddies,

Can we implement Von Mises yielding criterion in FLUENT. I know we can do that in FLOW-3D. Briefly, Von Mises yielding criterion is as follows:
in which D is the strain rate tensor,\tau_0 is yield stress and \Piis the second invariant of the extra-stress tensor.
Thank you.

Any help will be highly appreciated!
