In Openfoam for LES I know that you can implement a function in the controlDict file which calculates average velocity at each point based on all the time steps. If this is not implemented before the simulations begins, is there a way to do this now the simulation has finished ? FoamCalc perhaps?

Hi Ollie,

for run time averaging: have a look at the fieldAverage function
PS: sorry i misunderstood your post. i am not aware of an existing post pro averaging tool. but writing your own shouldn't be too hard.

The only problem I found with this postaverage utility is it only uses the time data you saved, opposed to the fieldaverage function in run time that uses all timestep data.
