How can I calculate Vorticity (or any vector quantity) in cylindrical components in CFX-Post?
Some quantities, such as Velocity, can be generated automatically in cylindrical components by CFX-Post from the Turbo tab. For other vector quantities, such as Vorticity, you can create the expressions and new variables manually. Using Vorticity as an example the expressions are:
theta = atan2(y, x)
VorticityAxial = Vorticity Z
VorticityRadial = cos(theta) * Vorticity X + sin(theta) * Vorticity Y
VorticityTheta = -sin(theta) * Vorticity X + cos(theta) * Vorticity Y
You can then create new variables based on these expressions.
