Detailed Description

The fields shared with tetwild and triwild live in wmtk::OptimizerParameters.

Constructor & Destructor Documentation

◆ Parameters()

wmtk::components::simwild::Parameters::Parameters ( )

inline

The four shared fields where simwild deliberately differs from tetwild/triwild. Set here rather than in the base so the divergence is visible in one place; each matches the default in simwild_spec.json.

Member Data Documentation

◆ check_envelope_at_init

bool wmtk::components::simwild::Parameters::check_envelope_at_init = false

Verify at init that every surface edge starts inside the envelope (2D remeshing only).

The same check triwild carries, and the same trade: the invariant is real, but it costs one sampled segment query per surface edge, serially, on every run. Measured in triwild's 2D sweep at 22s on a 3.5M-edge input and 5m07s on a 7.6M-edge one – 8.5% of that model's entire budget, spent before the first iteration. Off by default.

The 3D counterpart in VolumemesherInsertion is deliberately NOT gated by this: it is not a check but a decision, feeding the "rebuild the envelope from tet tags" branch.

◆ order2_envelope_ratio

double wmtk::components::simwild::Parameters::order2_envelope_ratio = 0.5

Order-2 (open boundary / non-manifold edge) envelope thickness, as a fraction of the surface envelope's. Deliberately below 1 where the surface envelope uses the full eps; see the doc on /order2_envelope_ratio in the spec for the measurement behind 0.5.
