Calculation of vorticity

[Niceno]

Dear guys,

In T-Flows, vorticity is calculated in two subroutines: Calculate_Vorticity and Calculate_Shear_And_Vorticity. I thought that one was too much, but by looking into them, I realized that vorticity is not calculated in the same way in each of these functions 😨

Which one is correct? What shall we do?

Dear Boki,

As far as I can see vorticity is correct in Calculate_Shear_And_Vorticity(grid), and I suggest to keep this one.

I see that Calculate_Vorticity is called only before Spalart's models. I have no idea why would one make a differentiation. Do you maybe remember Muhamed?

To my memory, I believe that I introduced Calculate_Vorticity while working on my thesis. Muhamed might have been using this function for Spalart's models, later introduced his Calculate_Shear_And_Vorticity for other advanced RANS models, but original Calculate_Vorticity just keeps hanging around.

Could that be the case?
