Quality statistics in the metric space for generated volume mesh.94 % of the edges has length between [0.5,1.5].

For the mean ratio 96%,of the elements have quality higher that 0.7.

Quarter of a Cylinder

Metric given by Qcircle metric.png

where hx = min(0.002 5^a, hmax), hy = min(0.05 · 2a, hmax), hz= hmax, hmax = 0.1, θ = arctan(x,y), a = 10 · | 0.75 - √ (x2+ y2 |
