HI all,
i'm new to Fluent. recently i got one cfd problem from my guide. the dead line is friday, Please help ..

The Problem is very simple.
* a 3d cylinder of any diameter
* external flow over the cylinder with a given velocity
* Find the drag coefficient
* the dimensions and properties like viscosity can be assumed.

what i have done
* i already created a cylinder wall enclosed in a box.

What i Need is
* couldn't create a fine mesh near the cyinder wall
* i don't now which solver should be used.

Please help me. by providing specific tutorials or any advice. as soon as possible.since i don't have enough time to the dead line.
