I want to thank the CFD Online community for accepting me. I would like to share that I am beginning my work on Ansys 12.1 fluent workbench and am looking for some really interactive and fruitful tutorials regarding generating 2d as well as 3d geometries. As I was going through the initial stages, I get stuck at the meshing section "No valid bodies". Kindly share with me information on the same. Once again any help is appreciated.

Could you post screen shots of the problem?

Start with the tutorials provided by Cornell.

Also you should probably start reading this:
This will help you in deciding what kind of model to use for turbulence, what type of solver to use and other aspects during your simulation. Also focus on meshing. Grid generation is one of the most important aspects of cfd, trust me on this, if your mesh is not right, you could get stuck on a problem for days.

can anyone teach me how to create the geometry for a 2-D lid driven cavity in ANSYS 12.1?

Please and thanks.
