Calculate pressure between internal faces

Hi,
I have a pipe-flow type simulation in which I want to measure the difference in (total)pressure between two internal surfaces. Usually this is done in fluent which allows internal surfaces to be defined, and hence one can calculate pressure and velocity etc on them. But since OF doesn't allow internal surfaces I have defined two faceSets (through fluentMeshToFoam -writeSets). I have discovered OF itself can't really do anything with these, but the swak4foam package supposedly can. But there seems to be something I have missed, because not even swak4foam can read the values on the faceSet. The functions part of my controlDict looks like this: Code:
functions ( averagePresInlet { type swakExpression; valueType faceSet; setname sec_inlet; expression "p"; accumulations ( average ); verbose true; } ); Code:
--> FOAM FATAL ERROR: Could not find a field name "p" of type scalar (neither type surfaceScalarField nor volScalarField) Autointerpolate: 0 Thanks, Klas |

Nvm,
found out that you need autoInterpolate true; Br, Klas |
