Switching off inertia
 

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

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
