[mesh manipulation] refineMesh ... but the opposite

Dear all,

While post-processing some results from a grid convergence study, I've noticed my coarsest grid was too fine for my purpose and no clear conclusions can be observed.

My problem is a benchmark of a 2D-CUBE. Instead of calculating the first cell distance from wall for the different directions away from it, and the new distributions along the cube's side, I was wondering if there is a fast&simple way of coarsening the mesh with some OpenFOAM tool.

cheers!
