Analytic Metric Functions

Linear metric

Metric given by Linear metric.png where hx =0.1, hy=0.1, h0 = 0.001, hz = h0 + 2(0.1-h0)|z-0.6|

Cube linear.png Cube linear2.png Cube linear detail.png
Surface Mesh, cross-cut and detail of the generated volume mesh.
Cube qcircle edges.png Cube qcircle qual.png
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 |

Cube qcircle1.png Cube qcircle2.png Cube qcircle detail.png
Surface Mesh, cross-cut and detail of the generated volume mesh.
Cube linear edges.png Cube linear qual.png
Quality statistics in the metric space for generated volume mesh.

91 % of the edges has length between [0.5,1.5]. For the mean ratio 79% of the elements have quality higher that 0.7.
