TetShape

The circumradius, the volume and the face area sum of the tetrahedron (a, b, c, d), in double precision, and whether it is degenerate: |det| under 1e-12 of its longest edge cubed, the test of the quality report.

In the namespace mesh::process. Declared in src/libs/libmesh/mesh/process/TetQuality.hpp.

Detailed description

The circumcentre relative to a is (|u|²(v×w) + |v|²(w×u) + |w|²(u×v)) / (2 u·(v×w)) for u = b − a, v = c − a, w = d − a.
