We set up the separator model, and stimulates the multiphase flow. After we ran the setFields, the following information occurred:

Setting field default values
Setting internal values of volScalarField alphaair
Setting internal values of volScalarField alphawater


--> FOAM FATAL IO ERROR:
Cannot find patchField entry for wall

file: /home/dell/OpenFOAM/damBreak4phaseFinelmxlmx/0/alphawater.boundaryField from line 34 to line 56.

From function GeometricField<Type, PatchField, GeoMesh>::GeometricBoundaryField::readField(const DimensionedField<Type, GeoMesh>&, const dictionary&)

Maybe the boundary conditions were set incorrectly, but we didn't know how to revise them.
Thanks so much for help!

hi
if you use blockMesh to create the grid , please check the blockMeshDict !
maybe there is not a "wall" in the boudary.

may you success!

We used the Gambit to model, and used the tool fluent3DMeshToFoam to convert.

we have solved this problem. the reason is that we wrote the capital letter W with respect to the word wall.

Thanks so much. The OpenFOAM is so strict.
I also misused a capital letter for wall.

Thank you, on my case is Inlet >> inlet

export geometry by Spaceclaim .stl with ASCII > cfmesh .fms > setFields solved.
