2-D Geometry/Mesh Generation

I am trying to analyze the flow properties over a 2-D wedge in a supersonic stream using Fluent, but I'm very new to the Ansys CFD package and I'm having difficulty figuring out how to create a 2D geometry and mesh. I have Ansys WorkBench 12.1 and most of the tutorials and online articles I've read on it so far all deal with 3-D geometries. I'm trying to analyze the flow over a wedge to get a feel for how to use Fluent because my ultimate goal is to upload a 2-D supersonic nozzle geometry I've created into Fluent and analyze its characteristics. If you guys could recommend me some tutorials and/or articles that would help me figure this out, I would highly appreciate it. Thanks in advance.

I managed to make a 2-D surface of a rectangle with a wedge cut out at the bottom right in the Ansys DesignModeler. I made this into one body with two parts, one for farfield and one for over the wedge. When I imported this geometry in the Mesher, I was able to mesh each part differently, however, there is some error in my mesh as it won't let me save properly (when I save, that green check mark doesn't appear next to the Mesh button in the Project Manager). Also, I'm not sure on how to assign a fluid boundary and a solid boundary (i.e. label the wedge surface as a wall and the rest of the boundaries as fluid). If anyone can help me with this, I would really appreciate it. Thanks in advance!
