Hi everyone,
Lately I have been working on an algorithm for a two-phase solver to couple the pressure and velocity fields.
I believe that I have modified the pEqn.H file correctly, but I feel I am missing something obvious somewhere, as once I look at the time step continuity errors, my local error is always much larger than the global error:

"
time step continuity errors for sum local = 1.74033576902e-07, global = -9.93993329672e-21, cumulative = -8.2037380338e-16

"

Luckily, the simulation doesn't diverge but my local error never gets smaller than 1e-7 which is a bit odd for me.

Does anyone have any idea why this might be happening? I have a feeling that it should be something small and obvious that I am missing here ….

Cheers,
Mahdi
