3D Mapped meshing
 
Hi guys,

I am trying to mesh a simple 3D rectangle. I want the middle section to have a finer mesh than the outter edges.

For 2D i used edge sizing then mapped the face. However when i try this on my 3D model it does not work.

I generate the model however i the following message:
"The following surfaces cannot be meshed with acceptable quality. Try using a different element size or virtual topology"



I would greatly appreciate any help. Or if someone can suggest another method that would also be great.:):)
