Dear All,

I am wondering how exactly Reynolds stresses are calculated in Nektar++. I have two questions regarding the calculation of reynolds stresses: 1) Whether these stresses are being calculated at every time step or just at the end of the simulation when we ask it to output the average field. 2) Once it outputs the average field then does it start from zero to compute the next average output field or proceed from the last saved output averaged field.

Any feedback would be of great help.
