Has anyone had any experience with setting up meshes in I-Deas to be used in Tgrid? Tgrid is a meshing program for Fluent. For some reason Tgrid does not want to recognize the groups that I create in I-Deas, eventhough it's supposed. Any help would be greatly appreciated.

Does anyone know of any methods for designing a bellmouth? Are there certain design constraints? ie. the radius is equal to half the radius of the inlet tube. Thanks for the help.
