Hello Angel,

The choice should be based on the machinery being simulated. If the definitions of hub and shroud are not completely straight-forward (e.g., a return channel) they may be set arbitrarily.

Best regards, Allan

Dear Allan thanks for your answer i input the shroud data with the format of: shroud ZR polyline

but the results display several shroud lines not one shroud line expected in the multistages-turbine,if i only figure one stage,there is not the phenomenon,should i change the input format?

I think the best thing to do at this point would be to send your AutoGrid template file to your local NUMECA support office. It may be just a formating error. You might double check the template description in the AutoGrid manual.

Best regards, Allan
