use the following CEL expression to create a variable which represents the Swirl Angles in any plane.


LIBRARY:
CEL:
EXPRESSIONS:
SwAnglePlane = acos((Velocity u *Normal X + Velocity v * Normal Y + Velocity w *Normal Z)/Velocity)
END
END
END

USER SCALAR VARIABLE:SwAngle
Boundary Values = Conservative
Calculate Global Range = Off
Expression = SwAnglePlane
Recipe = Expression
Variable to Copy = Pressure
