Detailed Description

Convenience subclass of AffineBodyConstitution for open triangle meshes treated as thin shells with a given thickness.

Uses the same UID as AffineBodyConstitution (OrthoPotential = 1 by default). Sets builtin::is_codim = 1 on the geometry meta so the backend uses the codim dyadic mass computation path.

Public Functions Documentation

function AffineBodyShell

uipc::constitution::AffineBodyShell::AffineBodyShell (
    const Json & config=default_config()
) noexcept

---

function apply_to

Apply the shell constitution to a 2D simplicial complex.

void uipc::constitution::AffineBodyShell::apply_to (
    geometry::SimplicialComplex & sc,
    Float kappa,
    Float mass_density=1e3,
    Float thickness=0.01
) const

Parameters:

• sc The triangle mesh (dim == 2).
• kappa Stiffness parameter for shape energy.
• mass_density Volume mass density (kg/m³).
• thickness Shell thickness radius r (effective slab thickness = 2r).
