Analytic Metric Functions

Linear metric

Metric given by where h_x =0.1, h_y=0.1, h₀ = 0.001, h_z = h₀ + 2(0.1-h₀)|z-0.6|

Surface Mesh, cross-cut and detail of the generated volume mesh.

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

where hx = min(0.002  5^a, hmax), 

h_y = min(0.05 · 2^a, h_max), h_z= h_max, h_max = 0.1, θ = arctan(x,y), a = 10 · | 0.75 - √ (x2+ y2)  |

Surface Mesh, cross-cut and detail of the generated volume mesh.

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.
