Excuse me,

I want to set up a case to estimate the effect of stirring on the flow field on the logitudinal section.

I use the case of 2D asymmetric swirl.

I plan to add a tangential force of 40N/m3. But I notice the governing equations in cylindrical coordinate is a bit complex.

So I wonder if the source term of tangential momentum is 40, or the 40N/m3 should be transformed additionally.

Thanks!
