time-averged velocity for LES

Hello everyone,
I am using LES to simulate a flow inside tube. I used a sinusoidal input waveform for the inlet velocity. In the CFD-post, there are two velocities, Velocity and Velocity.trnavg. I plotted a contour of velocity.trnavg at the peak time of the cycle. How does CFX calculate velocity.trnavg in this case? Is that done by time-averaging the instantaneous velocity from the beginning of the cycle to the peak time where I plotted the variable? Thanks in advance, |

Velocity is the instantaneous velocity. Velocity.trnavg is the time averaged velocity over the averaging time - if you have not defined an averaging time it will be over the entire simulation time.
