[BladeModeler] Blade ExportPoints & Hub/Shroud Offset

gdimitris · July 7, 2017, 14:10

Hey guys,

I am using design modeller to import the geometry of a blade from a cad file, then using the flowpath and export points I will export the blade's geometry to a turbogrid format. The problem I am facing is, while I am trying to use the exportpoints, at the blade Surfaces -> Hub/Shroud Offset % the minimum value in my case that I can export the points is around 5%, which I think is a very high number!? So I have two questions:

1) Do I lose the part of the blade where it is below the green loop? (see picture)
2) How can I reduce the offset %

Thank you in advance

I'm also confused between this feature and the hub/shroud offset in turbogrid. Can anyone tell me the difference?
