heisenmech is on a distinguished road
Hi all,

I want to give NITA (with fractional step) a try to speed up my LES of incompressible flow over a flat plate. Its fast as expected but the continuity does not go below 1e0, oscillating between 1e00 and 1e01. P.s Time step is small enough for this particular case, around 1e-04s. Any thoughts? or recommendations on NITA?

Thanks!
