Dear foamers!

I am trying to use the drag model for ractingTwoPhaseEulerFoam : TomiyamaCorrelated, but after few steps of the resolution, I got this error message in the terminal:

--> FOAM FATAL ERROR:

request for surfaceTensionModel surfaceTensionModel.liquidAndGas from objectRegistry region0 failed
available objects of type surfaceTensionModel are
1(surfaceTensionModel.gasAndLiquid)

From function const Type& Foam:bjectRegistry::lookupObject(const Foam::word&) const [with Type = Foam::surfaceTensionModel]
in file X:/OpenFOAM-5.x/src/OpenFOAM/db/objectRegistry/objectRegistryTemplates.C at line 193.

FOAM aborting
----------------------------------------

Can any one please explain what is this surfaceTensionModel and where to put it? I tried to put it in phaseProperties in surfaceTension section but without success.

Thank you in advance,

Hi achref_rabhi,

I'm not sure if I can help you, but please post your phaseProperties file.

Kind regards,
Krapf

Hi Krapf
