Hello, all, I can reproduce this behaviour using one of my aerodynamic cases with different laplacian schemes and otherwise same settings (see the attachements). It has to be noted that the...

Hello, Arjun, thanks for the text recommendation, I will have a look into it. Yeah, I know MG methods are a complex topic and there are many different directions evolving at the moment. I was...

Hello, V, these were simple aerodynamic cases (2D, incompressible, RANS) and mostly hexa meshes. The case I was looking deeper into the performance of the linear solvers was a ground effect...

Hello, everybody, this is exactly the same experience I've made with my simpleFoam simulations. My best practice usually is setting tolerance for every quantity to 1e-9 or lower and relTol...

Something in the order of 1e-12 might be appropriate. Remember, your simulation is not converged if the residuals of just one equation...
