I want to generate a mesh by using the rotational symmetry of the geometry. So make a surface mesh of a cross section and revolve this over 360 degrees. Is this possible in ICEM CFD?

      Yes, this is possible in ICEM CFD. The procedure for this is: 1. Generate the geometry for the 2D cross section. 2. Create Part names for the each of the bounding curves 3. Goto Hexa and generate 2D Planar block. 4. Appropriately split and associate all the block edges to the curves. 5. Generate 2D surface quad mesh using the Pre-mesh. 6. Right click on Pre-mesh > Convert to Unstructured mesh This loads the unstructured mesh within ICEM. 7. Go to the Edit Mesh Tab. and select Extrude Mesh by rotation option giving appropriate inputs for the number elements. and the angle 8. Select both the Shell and Line elements, then perform the extrude. This operation will create Shell elements from lines and volume from shells,creating the BC patches from the part names specified for the original lines. From here, export the mesh to Fluent, CFX or other solver.
