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. Inconsistent_forcedata.png I'm also adding residual data and a checkMesh log. linear.png courant.png cont.png forceCoeffs.txt Inconsistent_forcedata.png |

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.
