Detailed Description

template<typename ScalarT>
struct terra::fv::hex::DirichletBCs< ScalarT >

Constant Dirichlet boundary conditions for the inner (CMB) and outer (surface) radial boundaries of the spherical shell.

Used by apply_dirichlet_bcs to enforce prescribed temperatures after each time step. The BCs are applied as a strong (pointwise) enforcement — boundary cells are overwritten with the prescribed value at the end of each explicit or implicit step.

Template Parameters

ScalarT

Floating-point scalar type.
