I saw these examples.so when each is used for determining the flow rate?
"Mass flow examples Usually OpenFOAM solvers define a face-flow field phi that only has to be summed on patches patchMassFlow { type patchExpression; accumulations ( sum ); patches ( inlet outlet ); expression "phi"; verbose true; } On faceZones this is a bit more complicated as the orientation of the face has to be taken into account: flowBeforeZone { type swakExpression; valueType faceZone; zoneName beforeFilter; expression "phi*flip()"; accumulations ( sum ); verbose true; }" |
