Hi all
I have been looking at the procedure of calculating mean quantities in lesInterFoam and oodles. The procedure is correct as long as the time step is constant, but as soon as the time stepping is based on a Courant number and therefor variable time stepping, the procedure breaks down. This is the case, since the size of the time step is not taken into account when making the average - instead it is purely based on the number of time steps included in the average. see /solvers/multiphase/lesInterFoam/averaging/calculateAverages.H. I am planning to make the correction myself at some point within a reasonable time, as I need this deltaT-based procedure. It will become available by then. Best regards, Niels
