Hi Jane,

Thanks for your quick reply.

There are two reasons why I'm trying to use small values for facet_distance.
The first one is I'm not sure of the definition of facet_distance. I had
assumed it was a relative value, likely based on the domain size, diagonal.
Also while reducing this value below the theoretical minimum value you
mention, I noticed improvement in the quality of the surface mesh. It is an
absolute distance?
Second reason is I also want to have very flat surfaces for my bounding box
surfaces (squares) as that would make my life easier for simulation. To tell
you the entire story, I ultimately need to give separate attributes for the
boundaries and one way is by detecting, after meshing, x=0,x=L,y=0,y=L
etc... faces. So if you have an alternative I'm more than interested.
Thanks!

Alexandre
