Hi. I have a question about monitoring solver performance. It seems information of some solvers are displayed (such as residual and iteration), while others are not. How can I turn on monitoring the residual of a specific solver? Many thanks!

That's a diagonal and source only equation the exact solution of which is source/diagonal with a residual of 0 and no iterations so it didn't seem useful to print this information on the screen.

Thanks for your help! Just make sure I get it right. Is it correct that the performace information of all solvers will be automatically displayed by calling 'solve' function?

Yes provided it is switched on in your .OpenFoam-1.1/controlDict file which it is by default:
