hi all
i want refine mesh in area of volume that i shown in figure with red color, please guide me, how do this??? i know using refinement or sizing, ...) but they dont solve my problem bacause only refined surface no volume, and using body sizing number of cell very high, whether exist way for refined this volume in arbitrary area?
thanks in advance

Really what you want is a hex mesh in this domain. An inflation/tet mesh will be very inefficient, a hex mesh will use less elements to get the same mesh resolution.

As your geometry is fundamentally a rectangle this should be quite easy to do.
