carrotlaw New Member Join Date: Aug 2010 Posts: 1 Rep Power: 0	I am currently trying to use OpenFOAM to simulate a open channel fluid flow case with the rheological property as follows: Shear stress: yield stress (as a function of the fluid pressure) + K * (shear rate)^n I note that the yield rate is inputted as a constant in OpenFOAM. Would that be possible for such rheological property be implemented in it? Thanks for helping.
