Extrude boundary layer mesh from the specific surface

Dear all, i want to extrude the boundary layer mesh from the following surface. However, the generated mesh in the concave corner is bad as marked in the figure. Please suggested me on how to solve this problem using extrude method or other efficient method. Note that the pw file is also attached here.

Best regards

Have you tried playing with the smoothing parameters?
There is a 'tutorial Tuesday' available for this.

If this doesn't help you can switch to T-rex.

What grid quality metric are you looking at to determine if that corner is bad? It looks just fine to me.

Thank you for your help. i have solved this issue with other method. The Trex method may be another way. All the best wishes!

Thank you for your reply. I think the shape of the mesh at the corner is long and narrow. i have drawn a structure mesh at ICEM, as shown below. I think if add a connector at the corner can solve this problem.
