[Gmsh] Orthogonality of unstructured quad mesh

[Feifei TONG]

Dear All,

I am working to create hybrid structured-unstructured quad mesh around
circular cylinders, similar to this in the chain of the email, as posted by
Rajib. But I found the orthogonality appears to be very weak. I have tried

Smoother Surface{'faceToBeSmoothed'} = 40;

but without any improvement. The geo file is attached, along with a
snapshot of the mesh. Could anyone help? Many thanks.

Kind regards,
Feifei
