Hi,
I am trying to set up an outlet boundary to be non-reflective for flows. I think that by setting the outlet constant pressure to be equal to that of inlet does not mean that the flows are not bouncing back at outlet boundary, is that right?
Currently I am having the following codes which seems not working correctly (the outlet pressure is set slightly higher than inlet; I also tried 0 or equal pressure at outlet, the result were wrong):
inlet = FlowSubDomain(inlet_boundary0, bc_type = 'ConstantPressure',func = {'p': Constant(12810)}, mf = self.mf)
outlet = FlowSubDomain(outlet_boundary0 ,bc_type = 'ConstantPressure',func = {'p': Constant (12820)}, mf = self.mf)
Does anyone know what I can write for the impedance outlet?
Any help is highly appreciated.
