Hello!

I am running some CFD simulations for arterial geometry. I want to calculate OSI, which is given by the formula in the figure.

Can someone please help how can I calculate this in ANSYS CFD Post processing?

As far as I have understood, the 'Wall Shear Stress' variable gives only positive values, hence I am not able to resolve this.

Thanks in advance!
