spanwise length

[liu]

Dear Community：
Why is the spanwise length in the Channel3D case set to 6 grid lengths, rather than being the same as the streamwise direction, which is 2𝜋𝐻?
code :”Vector<T,3> extend(lx, 6.*converter.getPhysDeltaX(), adaptedPhysSimulatedLength);
extend[2] += (1./8.)*converter.getPhysDeltaX();

Vector<T,3> origin(0., 0., 0.);
IndicatorCuboid3D<T> cuboid(extend, origin );” thank you
