Hi all,
is it possible switching off the non-linear term in interFoam?. Is it enough just comment out this line?

// + fvm::div(rhoPhi, U)

in UEqn.H. Because i did it but i got some strange behavior at the interface and i was thinking that maybe it is not consistent with the rest of implementation.

best regards

andrea

Any comment on this? For my types of applications (very low velocities) negletting the non-linear term is a usual assumption so i wondering if it's feasible switch it off.


best
