AtoHM is on a distinguished road
I have an issue with the geometric respresentation and meshing by turbogrid. See attached two images of my blade's tip geometry. I tried to apply an identical clearance with two methods: A) Normal Distance and B) Profile Number (which I specified in DesignModeler). While you can clearly see how B has a constant clearance height, A's shape looks strange in the region before the trailing edge.
I already tried setting shroud representation to piece-wise linear. As I want to apply the clearance as an actual value rather than span, I would like to use method A and have to resolve this. Any suggestions on how to fix this?

Thank you in advance.
