Hello,

For my twisted rotor blades, when I attach the boundary layer to blades walls and then view 3D boundary layer, the hex elements are ok near the trailing edge. They are round and smooth. But when i cooper this volume with one of the source face pre-meshed as Quad/pave, the same elements very near to trailing edge become highly skewed. I could not figure out why this happens. The source faces are hub and casing. I also tried using TGrid scheme with hex elements near the blade walls and tetrahedral away but still could not control the skewness of the cells. any suggestions many thanks,

Try with size function.
