Hi Rob,

Thank you for the reply, i have completed that tutorial before. 

However, is .gtm file the output from turbogrid ?

Would it be possible to arrange a video call with you and screenshare, as I'm not sure and cannot find anywhere online how i can creat Turbo Grid mesh with Tip gap.

I'm using design modeller to prep the axial rotor geometry, should the tip gap be defined in the design modeller or can it be defined in turbogrid ?

Best Regards,
