Average Pressure Coefficients in Star-CCM+

faceres97 · July 6, 2022, 16:08

Hello all

I ran a LES and RANS simulation on a turbine blade and would like to plot the average pressure coefficients for LES. I have plotted the instantaneous pressure coefficients for LES but I do not know how to average the results. Any help?

I attached a screenshot of the plot.

Bests

Hi,
I noticed it has been some time since this has been posted. I do not no the answer but i am looking for it. have you happened to figure it out elsewere?

Create a monitor, select the type of average you want. Note that you need to run the calculation to collect samples, so you must do this before running and not after-the-fact.

I recommend to create field averages for each variable of interest: pressure, temperature, velocities, etc.

Then you can create the plots and select these new averaged variables instead of the instantaneous "pressure" or "temperature"
