Hi,

I am upgrading my simulation from OpenFOAM version 4.1 to version 6.0 and after doing so, I am now unable to control my residuals in fvSolution. I am aware that PIMPLE was upgraded for v6 and that the "residualControl" variable name has been changed to "outerCorrectorResidualControl" and I have updated my fvSolution file as per PIMPLE residual control not workin in OF. 6.0

Would anyone be able to point me in the direction of where I am going wrong? I'm sure it's something fairly simple but I would appreciate the help.

My fvSolution file is below:

Issue solved and due to stupidity on my part.

I hadn't updated the HPC job submission script to use OFv6 and therefore, the simulation was being performed using OFv4.1. As I had changed the "residualControl" to "outerCorrectorResidualControl", PIMPLE was defaulting to 10 iterations.

Cheers,
