Need help with meshing

Hi, I've been working on a project involving a 3D model of a room with two inlets and two outlets. In the end I want to track particle movements and concentrations of different gases. I meshed each imprinted inlet and outlet and then I meshed the body as a whole.
My question is, how can I create a finer mesh where the velocity is high and a coarse mesh where the velocity is low? I want to have my solution converge and right now it does not. I'm also using the student version which reaches a maximum of 512000 cells, so I want finer mesh only where it is necessary. In the picture you can see where the velocity is high and where it is low. not sure if the picture worked so here is the link. http://imgur.com/vAHniNA Thanks. |

Is there anyone that can help me? I would like to mesh the bottom halfof the room with a fine mesh and the upper half with a coarse mesh. Does anyone know how to do this?

I would like to have a min element size of about 0.05 and a max of about 0.1.

Say if you want to refine only bottom half of the room, draw a cube of its dimensions in the design modeler. In ansys meshing,use sizing function -> body of influence- > select the cube -> give the element size for refinement.
