Hello.

I am working with a type of fluidized bed using laminar twoPhaseEulerFoam.

I have gotten it to work with interstitialInletVelocity boundary condition, but I am now trying to include time oscillations in the inlet. I tried oscillatingFixedValue, but apparently it is not available for laminar (at least not in 20.06, which is the version I have). The error message I receive is:

--> FOAM FATAL IO ERROR:
Unknown patchField type oscillatingFixedValue for patch type patch

Does anyone know what would be a good boundary condition choice for generating a simple sinusoidal inlet velocity? Otherwise, how well do you think RAS would perform at low Reynolds numbers? Thanks.
