BuoyantPressure boundary condition
 
Dear Foamers,

I am currently working on a free surface case with interFoam.
I meet a strange problem when I try to use the BuoyantPressure boundary condition :

Code:

--> FOAM FATAL IO ERROR:
Unknown patchField type buoyantPressure for patch type patch

Valid patchField types are :

108
(
MarshakRadiation
MarshakRadiationFixedTemperature
advective
alphaFixedPressure
alphatJayatillekeWallFunction
atmBoundaryLayerInletEpsilon
calculated
codedFixedValue
codedMixed
compressible::thermalBaffle1D<hConstSolidThermoPhysics>
compressible::thermalBaffle1D<hExponentialSolidThermoPhysics>
compressible::turbulentHeatFluxTemperature
compressible::turbulentTemperatureCoupledBaffleMixed
compressible::turbulentTemperatureRadCoupledMixed
constantAlphaContactAngle
...

What I understand from my message error is that the buoyantPressure boundary condition type does not exist any more. Though I have found no mention of this anywhere. This type of BC is still mentioned in the user guide.

Maybe my installation of OpenFOAM is corrupted.

Anyone has already faced this problem?

Thanks for your help.

Did you put buoyantPressure in the correct file? Just a thought. ..

Hello,

which version do you use?

In the Version 2.3.0 the buoyantPressure was replaced by the fixedFluxPressure.

Thanks!
 
Thank you Matthew for your reply. Yes, this boundary condition was used in the correct file: ./0/p_rgh.

Thank you Michael! Yes I use the 2.3.0 version. It was one of my assumptions that this BC had evolved as it was not mentioned in the list provided with the error message. :)

Do you know where I can find this kind of information? In the release notes on the official website it is not mentioned anything on this subjectů:confused:

Thanks again,

Guillaume

Hello,

I think the only way to test somethink in this kind is to try it. I don't know were you can get the full information.

Hello dear,

You came to solve the problem ?. Find information BuoyantPressure boundary change if it was changed or replaced by another boundary condition?

as micha said, it has been replaced with fixedFluxPressure in openfoam230
