Deleting Internal Faces in a Mesh

I have a mesh which is composed of contiguous cubes, like this example (top right image):

I need to remove all the shared faces of the cubes, so the structure becomes one continuous solid.

Is there a way to select all the shared faces of adjacent cubes and remove them?

John or Star: can you tell me how you would remove the internal faces from the geometry created with this:

pdem = createpde;
g = multicuboid(40,40,0.1*ones(10,1),'Zoffset',[0:0.1:0.9]);
pdem.Geometry = g;
generateMesh(pdem, 'Hmax',4,'Hmin',4);

Thanks!

It’s difficult to be specific without your code, but if you’re using the surf function, see if:

surf( ... , 'FaceColor','interp', ... )

improves things.
