In the "Update Regions" section of the FLUENT Mesher, the named selections may not transfer over properly from SpaceClaim in newer versions of ANSYS. It is recommended that you double check which regions are which by mousing over the name of the region you are intend on selecting, and ensuring that the "blade_wall" region (the region corresponding to the interior geometry of the blade) is set to "dead". We have run into instances where this is named "fluid" instead of "blade_wall", so care must be taken to ensure that you are selecting the correct region when performing this step.
