CFD Analysis of a Smoking Pipe | Part 13 | Realistic codedFixedValue Condition ∇ OpenFOAM® v8

The following video demonstrates the set-up of a realistic »codedFixedValue« boundary condition in the #OpenFOAM framework for a more reasonable #cfd simulation. The rock-vapor classic (internal flow analysis) part 13 describes the usage of the »codedFixedValue« condition. However, during the set-up and the calculation, one will see that the mesh we created does have problematic cells/faces as we do have artifacts that will influence our numerical solution and in addition slow down the calculation as the velocity increases at one specific area drastically.


Topics of the realistic boundary condition are:
