I am getting the following error. Can anyone tell me what I am doing wrong.

--> FOAM FATAL ERROR : flux requested but p not specified in the fluxRequired sub-dictionary of fvSchemes.

Here is the fvSchemes file

That would be the following bit:


I'm not sure what the problem is: if you are running this case, it should work.

As there is only one thread on this subject I thought I would chip in for thread "completeness". I had this message (full error messages below) and eventually discovered that it occurred because I'd accidently introduced an extra "}" in my fvSchemes file. Once removed the message disappeared and it ran fine. OF1.4.1.

default none;
laplacian(DnuTildaEff,nuTilda) Gauss linear corrected;

I checked my fvschemes file again. There are no errors in the file and I still have this problem with the cylinder case for reactingparcelfilmfoam solver.
Any idea what is going wrong here?

flux requested but deltaf not specified in the fluxRequired sub-dictionary of fvSchemes.

From function fvMatrix<Type>::flux()
in file /root/OpenFOAM/OpenFOAM-2.4.0/src/finiteVolume/lnInclude/fvMatrix.C at line 887.

FOAM aborting

I have declared deltaf in my fvschemes file under fluxRequired section.
