  Dear colleagues,
  
  I have a question regarding to local mesh on a surface of solid body.
  
  In my problem, I would like to have local mesh refinement over the first layer under cylinder.
  
  A picture is shown for more illustration.
  
  I am wondering if you can send me your suggestion.

  Is that a separate surface from the solid? Delete that. Are you using SpaceClaim? If so, just start a sketch on the top face of the top solid and draw that rectangle. The face will be split into two faces. You can then apply a sizing mesh control on that rectangular face.

  Thanks for your prompt response.
  
  As you said I did it in spaceclaim and I have deleted the surface.
  
  Then I made a new sketch on first layer (Brown layer). When I open it into mechanical structure to generate mesh, it looks like a new surface.
  
  This new surface requires thickness. Actually, I would like to have mesh refinement inside this rectangle on brown layer not only on rectangular surface (green surface in bottom picture).

  It doesn't look like you deleted the surface in SpaceClaim because I can see it in Mechanical. You can suppress that in Mechanical.
  
  If the brown solid does not have a face in the shape of a rectangle, then you have not been successful in SpaceClaim.
  
  The sequence is:
  - 1) Click the Sketch Tool
  - 2) Pick the Top face of the brown solid
  - 3) Draw a Rectangle
  - 4) Click the 3D button.
  The result should be the top face of the brown solid is split into two faces.

  Thanks for your helpful answer.
  
  I have tried to use projection tool on spaceclaim. It was helpful to make mesh refinement.
  
  Now I have used Gasket mesh. I would like to increase mesh layers in each part.
  
  For example in bottom part (grey) there is only two layers of mesh. How I can increase the number of mesh layer by Gasket mesh.
  
  Thank in advance

  Don't use Gasket mesh. Use a Method = Sweep and you can define the number of elements in the sweep direction. You can set the sweep direction be selecting the source faces.
