Visualizing force of a domain in potential flow

bunya · June 6, 2011, 09:48

Hi,

My homework is to simulate two spinning cylinder in potential flow in 2D.(Flettner rotorship)
I successfully got the velocity streamlines, and pressures, which are nice and beautiful.

Additionally I have to visualize the resultant forces developing on the two rotating cylinder. Eg: One vector from the center of each cylinder.
Is there a way to do that in CFX-Post?

Yes. Use the function calculator to give you force_x, y and z.

And then? Can I draw vectors based on that data within Ansys, or my only chance is to use an external software (eg inkscape) to draw into exported images?

What are you trying to do? If you are just trying to produce an image with the total force vector shown in the right direction then use photoshop.
