Hi,

I have a question regarding the continuity errors in OpenFOAM. What is the difference between the cumulative continuity error and global continuity error.

Regards,
Christian

Hi Chris,

cumulative is the sum of the global error over all the corrector steps in your simulation.

You can see this at the beginning of your simulation (first corrector step global is equal to cumulative, second corrector step cumulative is equal to sum of global first and second corrector step etc.)

Cheers,

Steven
