meshing.diagnostics.triangle_quality

meshing.diagnostics.triangle_quality(mesh)

Triangle shape statistics: minimum angles, aspect ratios, degeneracy.

The aspect ratio is the longest edge over the smallest altitude (l_max^2 / (2 area)), which is 2 / sqrt(3) ≈ 1.155 for an equilateral triangle and grows without bound for slivers. Triangles with area below 1e-12 are counted as degenerate and excluded from the percentile statistics (which are nan if nothing remains).
