Hello OpenFOAMers,
I run a simulation but it seemed to me that there was not enough samples so I run more time steps from the last saved time. However I have got a different signal, and confirmed by a the same simulation run form 0 to the new end time. I did not do reconstructPar because it was simply to run the same case in the same number of processors. However I have other cases where I did the reconstructPar and then the decomposePar -force and a shift is present. Does anyone know what this might be ? Thanks in advance I have attached some examples with the data from the probes. (Forgive me if I did not put the images in the usual way.) no_reconstruction_fewsamples.jpg no_reconstruction_more_samples.jpg reconstruction_shift_0.jpg reconstruction_shift_1.jpg reconstruction_shift_2.jpg

Hi guilha,
There are several possibilities that come to mind, so to list just a few:
Best regards, Bruno
