Hello All,

I am getting this following error when I try to run an existing OpenFoam case setup. I request any of you to please advise on fixing this issue.

Hi,

My guess is that in 'p' you have given zeroGradient at all boundaries. From what I know you need to set value of pressure at least at one point so that you can get well-defined system that can be solved. Just add these two lines to your fvSolutions in the SIMPLE block:

pRefCell    0;
pRefValue    0;

Cheers,
Antimony

Thank You for this! It really works!
However I don't know what values should I give in pRefCell and pRefValue. I got this error while using simpleFoam on lid driven cavity. Inserting this in Fv solutions removes the error but the results don't show any pressure contours . Is it the 0 pRefValue that is giving no pressure contours or is it something else?

Thanks

I've got the same problem
