Problem with 2D ICEM mesh check in fluent
 

Hello everyone! I created a 2D mesh in ICEM but when I import it in fluent 6 I have a warning during check mesh: "mesh has negative volumes!" What's the problem? If someone can help me I thank him very much.

It's not a problem of Fluent. It means that your meshing is not good, try to decrease the size of your cells. For 2D meshing I use Gambit but It's the same problem, size of cells too big for your geometry.

The size of cells are too small and not too big. Coarsen the mesh near the wall but take care u dont coarsen it too much - for the gradients are quite significant near the wall. Are else create the geometry by specifying the dimensions in mm in ICEMCFD. (its like mentioning for 1mm specify 1000mm or 100cms) try importing it to Fluent and then set the scale in fluent and then do the analysis.
