I am sorry that I choosed a wrong icon for my thread, now I have to post it againt with a question icon.
Good afternoon everyone~
Today I am using OpenFOAM to caculate an axi-semmytric flowfield.
After checkMesh ,the following message came out:

--> FOAM FATAL IO ERROR:
inconsistent patch and patchField types for
patch type wedge and patchField type zeroGradient
file: /opt/OpenFOAM-2.3.0/FOAM_RUN/tutorials/nozzle/0/p.boundaryField.wedge_front from line 48 to line 48.
From function fvPatchField<Type>::New(const fvPatch&, const DimensionedField<Type, volMesh>&, const dictionary&)
in file /home/sergio/rpmbuild/BUILD/OpenFOAM-2.3.0/src/finiteVolume/lnInclude/fvPatchFieldNew.C at line 172.
FOAM exiting

Does this mens that I set a wrong patchField type(zeroGradient) for my patches typed "wedge"?
If this is the problem, where can I find the correct patchField type for "wedge" patch?

That's all, thank you ~

Hi,

You have indeed read the error message correctly. For a wedge patch all the fields should have a fieldType wedge, like this:

boundaryField
{
    wedgePatchName
    {
         type           wedge;
    }
}

This is similar to the empty patches in many of the tutorials, but instead of "type empty" you should use "type wedge".

Regards,
Tom

Hi, Mr. Tom:
your methord solved my problem and I've learned more about "empty", thank you very much.

thanks.

error>>inconsistent patch and patchField types for
patch type empty and patchField type zeroGradient

This tells you that the type in constant/polyMesh/boundary is set as empty. This means all your variables need to have:

boundaryField
{
    patchName
    {
         type           empty;
    }
}
