Hey guys,
So I have a really interesting issue. I want run a 2D FSI by basically having a 3D geometry being only 1 element thick. Although there are several ways to do this, I found the best way was to simply extrude the 2D sketch out a set distance, and then use the Sweep method in the Ansys Mesher to create a geometry that is only 1 element thick. Here lies a problem, however, I'd like to have inflation on the walls, as well as control the sizing in certain areas I care about. After playing around with this for a few days, I found the best way to do this was to divide my geometry up into different bodies, and then use the Edge Sizing feature to get my desired resolution.

So, cool, I made a kind-of ICEM-looking mesh by using the Ansys Mesher (check out the figure). I know the nodes don't match up (any suggestions on that would be cool), but I think it looks nice.
The problem, then, comes into play when I import this into Fluent. Due to me having several bodies, I now have dozens of interfaces. What's more, the regions that I would like to be my inlet and outlet are now divided up into different parts, which probably isn't good.

So, now my question is, how do I merge all of these meshes into one big, beautiful mesh at the end? Or, is there a better way to do what I'm attempting (please don't say ICEM, as I have no experience with that and found the learning curve to be quite large).
