Dear experts,

My Geometry (old case () is a single blade inside a big 120o enclosure sector , after long period i'm stuck with T-Grid skewness problem around the blade surface which appear strongly in Fleunt (after send my file from ICEM). The ICEM T-Grid skewness is high but quality and skewness are good.

I'm using Tetra, unstructured and Robust (octree) meshing techniques, I need a recommended ways to improve T-Grid skewness in ICEM (not Fluent).

Note: I noted that if the total height of blade prism is large, T-Grid skewness will be good but unfortunately in my case the first layer is very small (4e-5) due to y+ condition

Thanks in advance
