Hi,

I m trying to validate the coeffiecients of forces for an airfoil but I am getting wrong values for Cl from the wind tunnel compared to the wind-tunnel results.

Everything is correct and fine. Except when i execute refineMesh I get this error.

--> FOAM Warning :
From function forces::forces(const objectRegistry& obr, const dictionary& dict)
in file forces/forces.C at line 164
No fvMesh available, deactivating.

Can some one help regarding this? I am attaching my blockMeshDict with this message

This is a Warning, not an error. At the point where your forces object is initialized, there is no fvMesh available. It will become active again when you run an application which has a fvMesh in memory. (refineMesh only has a polyMesh not a fvMesh)

Basically, ignore the warning.
