difference between inletValue and value in inletOutlet B.C.
Dear foamers
I try to run a case and have a problem with inletOutlet Boundary condition. What is the difference between the inletValue and value in this B.C.? It seems that they have a same value in most of the cases. regards, Moha:confused: |
inletOutlet is a back flow boundary condition for outlet. If fluid attepts to flow inwards, it applies a fixed value velocity assigned by inletValue for that given patch face. Or, it use zerogradient.
InletValue is the value flow inwards you have to give. value is the actual value for the given patch. given by inletValue or patchface neighbour cell(zerogradient). Hope this helps. regards, Junwei |
Thanks for your answer. It was useful for me.

Junwei, your explanation about inletValue is clear for me but the one for value isn't.

value is a keyword for all the numerical boundary condition. It is not used for input but calculated based on the boundary you set. It is useful for postprocessing. you can set the same value as inletValue, and it will be updated during the calculation.
sometimes, paraview don't like boundary condition without "value" entry. Regards, Junwei |
Junwei, thanks for the clarification and confirmation. Tthat's true when values are calculated "value" entry data is replaced by which is calculated at running time.
