Hello, I'm doing a steady flow simulation of a flow bench and I'm trying to calculate the Tumble Number with the Ricardo Formula


I'm having some trouble in calculating the Moment in my simulation in order to compute the Tumble number.
I have created a volume threshold in order to calculate the Moment in a specific region with a local Coordinate system (Tumble_cs) and I've calculated the angular momentum (Kg*m^2/s), with the following field function:

${Density}*${Volume}*($${Centroid}(@CoordinateSyst em("Tumble_cs"))[0]*$${Velocity}(@CoordinateSystem("Tumble_cs"))[1] -$${Centroid}(@CoordinateSystem("Tumble_cs"))[1]*$${Velocity}(@CoordinateSystem("Tumble_cs"))[0])

I've created a sum report of this field function computed in the threshold I was talking before.

By far I know that it could be possible to obtain the Moment in this region if I could compute the Angular momentum flux (Kg*m^2/s^2 = Nm).

Thanks in advance for the help
