Default 3D blockMesh with input/output patch

Hi all,

I'm currently working with/on the adjointShapeOptimizationFoam solver and i've got it up and running for a 2D case (See pictures velocity/alpha).

However, now I want to extend it into 3D and I think there must be a way to do it simpler. See attached my blockMeshDict file.

What I need is something like this, input/out may be square:

What I did is create 4 planes of vertices and made 27 blocks from that, but now I learned that if you create multiple blocks you have to merge the faces linking each other, that makes it quite a bit complex.

It should end up something like this, but as you can see the results make no sense yet since I havn't merged any patches yet (and probably other things).

Any help in the right direction or a simpler method is appreciated!

Cheers, Jeroen.

Fixed it, should've assigned zeroGradient/noSlip to the outer walls. However, it is still a rather complex mesh for a very simple goal, just an in- and output.
