CFD Online Discussion Forums - [Other] Mesh refinement

Hello,

I would like to refine a mesh next to a wall with several layers with a structured mesh. The problem is that my body is not a cuboid, so the refinement box doesnt fitt well.

My first try to solve the problem:

I have created a faceSet and then added all cells which are in contact with the faces to cellSet and then refined my layer. But this method works only with one layer.

Code:

{

        name    cells_wall;

        type    faceSet;

        action  new;

        source  patchToFace;

        sourceInfo

        {

            name "Front|Back|Top|Bottom|p1|Left|Right";

        }

    }



{

        name    cells_wall;

        type    faceSet;

        action  subset;

        source  boxToFace;

        sourceInfo

        {

            box (-100 -100  0) (100 100 100);

        }

    }

    {

        name    box;

        type    cellSet;

        action  new;

        source  faceToCell;

        sourceInfo

        {

            set     cells_wall;

            option  any;

        }

    }

Does anyone know how to do this with n layers? For example to select all cells which are in contact with the cells of "cells_wall" and add them to the cellSet?
