Modelling open channel flow with wave at the interface
I want to simulate open channel flows where flow velocity and waves on interface co-exist.
My 2D geometry is shown here:
I am using VOF model, clicked open channel flow & open channel wave BC options.
I am using pressure outlet at free surface and pressure outlet (Please refer the image) :
I am using velocity inlet in the inlet, where water is supposed to flow from along with wave at the interface. I have clicked open channel wave BC & Segregated velocity inputs, where I have provided velocity for the incoming water. Primary phase has no velocity. Please refer the image below:
However, the flow velocity does not get simulated correctly. I am able simulate waves at the free surface in the absence of water flow velocity. However, along with flow velocity, the simulation is not giving results.
Kindly suggest where am I making mistakes.
