Re: 2D mesh with viscous layer

Dear all,
I would like to make a 2D mesh (triangular or quadrilateral) of an external right angle.
To perform this, I use NETGEN 2D algorithm with the automatic length for the 1D hypothesis. Then I add a viscous layer on the two edges of my external right angle (see picture).
However, the mesh doesn't look good at the location iof the right angle.
So is it possible to improve this mesh. For example, in order to have rectangular faces everywhere in the viscous layer and thapezium (angle with a 45°) faces in the right angle location, I would prefer distributing the 45° angle all over the edge along my geometry.
Thank you for your anwers.
