Dear OpenFOAM Users,
I'm using OpenFOAM's pimpleDyMFoam (or unsteady pimpleFoam for OpenFOAM version > 5) to solve unsteady flow problems. To check the convergence of a simulation at each physical time step, I would like to extract the velocity and pressure residuals during each PIMPLE iteration (also called inner iterations or pseudo time steps). Does anyone know a quick way to do that? Alternatively, if anyone knows how to extract the forces and moments at each PIMPLE iteration that would also help a lot. Best wishes, Anouk |

The fvmatrix Class holds a function residual () which returns the residuals https://www.openfoam.com/documentati...1fvMatrix.html
