plotting grid-wise residuals
 

I would like to solve the convergence issue Im facing when I switch from k-epslion to RSTM by looking at which areas of the flow are problem-causing. Is there any way to see the residuals associated with each grid using paraFoam?

This is something I'm also interested in.
I know that with the in-house code FreSCo+ of the HSVA and TUHH residuals can be shown as grid related data in Paraview. This is sometimes very helpful to solve convergence issues by identifying weak points in your mesh.

Is this also possible in OpenFOAM?
