Default Fluctuations using LES

sihaqqi is on a distinguished road

I am using Fluent to capture pressure fluctuations in a developed turbulent flow. I have two geometries, pipe elbow and tee. I had been using openfoam and it would give pressure fluctuations at probe locations at every time step which would constantly fluctuate in time whereas in Fluent, they die in developed flow and flow becomes steady. I am taking different types of Surface Monitors. "Integral, Area-weighted-average, Sum" of "Static and Total pressures both" but to no avail. I am using Smagorinsky Model with Velocity 75 m/s and using No perturbations method.

Also I am using Sampling from command line for those points but somehow I cannot execute compute-sample in report and plot both, Can someone please write the whole syntax.

Best Regards
