Hello,
i have a question about meshing a blade in Turbogrid. In the two pictures you can see two different blades. These were meshed in Turbogrid. My problem is, that the passage boundarys are not at the same position. In one case the blade is centred and in the other the blade shifts to the top. Is there any option in TG that I can adjust the centred blade with the same angle ? In Post I wanted to compute expressions in circumferential direction (theta). But with this shift they aren't that good to compare. Thank you very much! |

Yes,
In Geometry > BladeSet Options and way down there is an option called "Bias of Blade towards High-Periodic". Its normally set to 0.5, which means centered between the periodic boundaries, see what fits your case best. |

I have a new problem. When I change the value, only the outline changes. The topology and the mesh stay centered. I have tried many things, reread every tab and even imported the curves new, but it won't update the topology to higher periodics.
Is there any trick ? |
