[alinve]

Dear All,

I'm trying to validate openFoam to simulate oscillating flow fields.
I want to simulate 2D channel flow with oscillating inlet velocity. I'm using icoFoam as solver, the velocity inlet bc that I want to imposed is of the form u(t)=a+b*sin(2pi*f*t), where a, b are constant, t is time and the f is frequency of oscillation. Moreover I've imposed 0 pressure at the outlet and no-slip condition at the wall.
I'v tried to used the oscillatingFixedValue as boundary condition type for inlet velocity. The solution doesn't seem to converge. Have you got any suggestion? Has somebody used oscillatingFixedValue bc before?
Is it proper to describe my inlet condition?

Thanks in advance.
