Hello everyone, I want to simulate the swirl and tumble number along with the poppet valves flow coefficient. The swirl and tumble coefficients are calculated as the first imege shows.

In order to do so, I created a new Field using a function object, as described here: integrate multiplication of fields

My function object is as shown in the file "dMom.txt" attached.

Without putting the general coordinate, it works, it calculates the new field, my problem is to actually put the single cell coordinate in the calculation. I tried with some methods on internet, as the one tried in the file but I couldn't make it.

The swirl axis is the z one, and there's a -0.14 in the y because is the position of the axis of the cylinder.

Any ideas?
