Row 1 optimization failed
 
Hi everyone

i am still new in using autogrid 5, now my project is to simulate naca 4415 for wind turbine. during the generate 3d mesh, there are this error "Row 1 optimization failed", and the quality report shows a high negative cells, can anyone help how to solve this problem?

first step is to check your geometry. there may be some discontinuities.
other step that should be taken is to chek other meshing strategies such as HOH, HI...

regards

Hello is, we will look into this matter together with other member during class. We'll discuss on how to improve this simulation by gaining any necessaries for it. Izzul.
