The mesh region can now be converted to a two-dimensional one. There are special requirements in STAR-CCM+ for three-dimensional meshes that need to be converted to two-dimensional. These are:
The mesh imported for this tutorial was built with these requirements in mind. Were the grid not to conform to the above conditions, it would have been necessary to realign the region using transformation and rotation facilities available in STAR-CCM+.
Once you have clicked OK, the mesh conversion will take place and the Geometry Scene 1 display will show the two-dimensional geometry in the Graphics window. (If the image does not appear immediately, simply click the 
(Reset View) button on the toolbar.)
All the geometry parts will be shown, viewed from the +z-direction. The mouse rotation option is suppressed for two-dimensional scenes.
