hi

I'm simulating 3D vertical axis wind turbine. in mesh generation minimum orthogonal quality is about 0.02 which is very low. i used inflation and face sizing on the walls of blades. I've changed sizes several times but it didn't work.I insert some images of my mesh. how can i improve min orthogonal quality?

thanks

please check following which may help you. 

you will need to identify first where are bad cells i.e. cells below ortho qualty of 0.1. then use different options like geometry modificaiton, face/edge sizing etc to get rid of bad elements.
