problem about flowPath feature in bladEditor
 

hi
guys, I have made my centrifugal impeller model in solidworks ,but it is so hard to mesh it in ICEM CFD,so i choose to mesh it in turbogird,in order to export the impeller geometry to turgird, I use the bladEditor in ansys design modeler. first ,i have to use the flowPath feature to create(specify) the flow path, I'm sure about the inlet/outlet/hub/shroud contour,but how can I decide the layer contour ? for example, how many layers contours? the shape of the layer contour ?
thanks

which tutorial you are following?

it is not a tutorial in the help documents， and i have solve the problem ,just right click on the layer hub or shroud to choose add a lower(upper) layer,then the bladeditor will add layers automatically. thank for reply
