Hi Folks,
I am currently trying to model a 3D vertical axis turbine with straight blades using Ansys 14.5 and Fluent, I have booleaned out my blades and shaft from the rotating domain all went to plan.

however when I try to mesh in Ansys mesher I get the warning "Inflation created stairstep mesh at some locations" when I create a section and examine the mesh I can the stairstep is created towards the trailing edge (see attached)

I have searched this forum and it is suggested to change the angle to 180 degrees from the default of 140 degrees, I tried this and it didn't work.

I'd appreciate it if anyone could help me with this problem.

Regards,
Dave
