I am looking into settings for PIMPLE for reactingFoam for both non-reactive and reactive cases.

Please find attached a plot of the converge of the non-reactive pre-processing part of the Sandia_LTS tutorial case.

Why does the pressure residual oscillate?

Or these oscillations physical or numerical?
