Hi all,

I need a BC that can specify the face values for each cell face at each time step, that is saying that the BC must be spatially and time varying.

The catch for my case is that i also need the BC to switch between fixedValue and zero gradient when the flow is entering/exiting the solution domain.

I have already tried and worked with TimeVaryingMappedFixedValue BC type, it works as expected. But as it is FixedValue type, switching seems not possible. The mixed BC type inletOutlet does that switching and also can be spatially varying when inletValues are provided as a non uniform vector list, but lacks the unsteadyness.

Can anyone guide me to develop this kind of BC as i am stuck?

Best Regards

P.S i am currently trying to couple inletOutlet with timeVaryingMappedFixedValue in order to do that but haven't succeeded yet due to my limited understanding of OpenFoam and C++
