Hi all.

I'm simulating a flatplate in cross flow using pimpleFoam. My mesh seems to be fine. I got the results for Cx and Cy and later on decided to use a different value of Aref. So I changed the Aref value and ran execFlowFunctionObjects to calculate the force Coeffs. The results I got are not as expected. To depict the difference in results I used the same scale as was used for run time postprocessing and plotted the results again.

Take a look at the plots below. I'm unable to explain why the periodicity of the force Coeffs has changed. Both graphs should be the same instead they are different.

I'm also adding residual data and a checkMesh log.

I found the answer guys. Run time post processing has access to all the timesteps. Post run post processing has access to only the written time steps. Sorry for the post.
