Coarsen 3D Grid ??
 
Hello fellow Fluent users,

Is it possible to coarsen a 3D grid in Fluent at all? according to the manual (23.8.3) not really: "Note that if you are using hanging node adaption (the default), you will not be able to create a grid that is coarser than the original grid. For this, you must use conformal adaption. Note also that conformal coarsening is only available for 2D or axisymmetric geometries."

I want to adapt my grid to correct Y+ values, however I can only refine it..

Any comments would be greatly appreciated

Stephen
