Geometry Error in TURBOGRID

Hello everyone

Hope you all are doing well!

I am quite new to the simulation regarding the Turbomachines. Right now, I am simulating a 2-stage turbine. I have the co-ordinates for hub, shroud, blade profile. I tried to import the file to Turbogrid but I am getting an error stating that "Start and end parametric value are identical". I tried searching for solution but unfortunately couldn't solve it. It would be great if you could assist me in this issue.

Thanks in advance.

Not the right forum for that but anyway, could you post the hub and shroud curves so we can inspect them?

Hello Stel

Thanks for the response. I was able to figure out the mistake I made. I selected the principal axis as "Z" instead of "X". Now I am able to import the geometry.
