[firedrake] Anisotropic mesh

[Anna Kalogirou]

Dear all,

There seems to be a problem with anisotropic meshes, namely with 
different number of nodes in each direction. The problem is encountered 
closer to the x-axis if the x-direction has less points. The situation  
becomes even worse if I make the domain rectangular and as its length is 
increased.

You can see an example in the attached code which uses 
UnitSquareMesh(20,80) on a rectangular domain 4 times longer than wide.

I am not sure why this is happening, so hopefully someone can help.

Kind regards,


Anna Kalogirou.

P.S. Does Firedrake support the use of quadrilateral meshes?
