Default Continuity residual + solution adapting

Hi,

Whenever I co a grid independence test I find that although most of the residuals converge to the same level as before the grid test, the continuity residual never converges to the level of the preivous test. It still converges to a level 5e-05 but the previous levels were 1e-06 and 6e-06.

I'm using solution adaptive method with cell increases of approimately 100,000cells each time.

Should the residual converge to the same level as before?

Is there a problem with the grid?

Regards,

Eric
