how to decide the shroud and hub line
 

hi: i want to know how to decide the shroud and hub line in numeca?

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
