Hi all,i have modeled a Rectangular parallelepiped with two mass flow inlets at each end face ,a pressure outlet at other only face.k-e viscosity model. split outlet into to two equal half . while continue equition has converged and total mass flow rate of outlet is steady,but the mass flow rate at each half keep fluctuating. how it can be? how can i accelerate it to steady thanks in advance andy P.

What kind of numerical discretization do you use for the problem.?

i pick the segregate solver SIMPLE pressure-velocity coupling discretization.it deals with a ordinary steady problem.
