Hello,


I have done a structured mesh for a fan blade passage including the hub, and after this step I will add periodicity in vertices. Before that in the blocking strategy , I have a problem with the angle of the elements as shown in the picture. As you can see, there are 2 bad angles in the geometry that are responsible for the problem . But because this geometry is necessary for the periodicity, I cannot change it. So, is there any way to improve the angle quality? Like doing any o-grid or following another blocking strategy or something else?



I also upload the the files of my mesh. Any help would be appreciated.
Thanks in advance.
