Default gradient at the border

Dear everyone,

Sorry for the stupid question: I am new to both Finite Volume and OpenFoam.

I am solving some classical elliptic equation. The solution is a volScalarField. I also compute the flux, ie a volVectorField, through fvc::grad. Everything is fine except the value of the gradient at the border cells: much higher!

I guess I am doing something wrong, but can't manage to find what.

Many thanks in advance for your help,
