One of the ways to go about this would be to use the history points option. You would get your instantaneous velocity and pressure ields at certain timesteps written into a history file On Wed, Feb 21, 2018, 4:53 PM <[email protected]> wrote:

Hello,

Thank you for the reply. I am aware of those lines are intended for time-averaging. I was wondering if anyone could teach me how to generate the instantaneous velocity field

in a similar pattern like the following:

open(unit=56,file='vel_fluc_prof.dat')

write(56,'(A,1pe14.7)') '#time = ', time

write(56,'(A)')

& '# y y+ uu vv ww uv'

Thanks a lot,

Tim ------------------------------

this is not really instantaneous data, but rather statistics. Then you

would need to run some kind of averaging (in time, space etc.) and

proper postprocessing afterwards, which strongly depends on the actual

flow case. I am sure that there are people in this group that have done

this type of analysis for a variety of flow cases/geometries.
