Hi guys,
Can someone please explain, line by line as much as possible, with a very simple geometry like Rectangle, how to
(1) Create a Mesh in ICEM 12 and Generate .msh file
(2) Open the Mesh in Fluent 12

I have read a number of voluminous tutorials that are not organised in one location. After creating my mesh it saves as .uns and Fluent will not read it.
When I tried using Fluent_V6 as the solver and I generated a .msh file, Fluent will crash while reading it with errors like :

Error: Build_Grid: no cells in case file and at times no zone or cannot read file.

This is really frustrating...
