Accuracy
 

Hi guys,

I´ve started this thread because I´m not sure about my blocking. I´ve got the mesh of a blade but when I look carefully in the leading edge I don´t like what I see. I know this is about blocks shapes but.. can I adjust much more to the shape of the profile with this blocks? If I use automatic linear, for example, is it good or not? Is there any way to do this much more exact?

Hi. As far as I understand it, the solver does not recognize "bended" cell walls. Cell walls are straight lines in 2d or planes in 3d. Thus, if you want to have a more accurate solution at strong bends, you need more points.

Thanks Philipp. I´ll do it.

Maybe someone else here has a different oppinion ?!..
