Hi everyone,

I want to apply the timeVaryingUniformFixedValue boundary condition to the outlet in such a way that the outlet is closed (Dirichlet b.c.) for the first 3 seconds then it is open (Neumann b.c. e.g. an inletOutlet b.c.) for the next 2 seconds and it continues like that.

Is it possible to apply derived boundary conditions (e.g. inletOutlet) in timeVaryingUniformFixedValue for the velocity? In other words just change from Dirichlet b.c. to Neumann b.c.?

Thanks
