How to calculate vorticity in cylindrical coordinate?
My simulation domain is cylindrical (3D axisymmetric), but the coordinates are defined in Cartesian.
After the simulation, I calculated the vorticity field using the 'vorticity' command. Then I got four quantities: magnitude of vorticity, the x, y and z components.
However, I want to calculate the vorticity field in cylindrical coordinates. Most importantly the azimuthal component.
Can anyone give some suggestions? Thank you!
