◆ getSecondDerivativeManager()

const BoundaryConditionManager & smith::DirichletBoundaryConditions::getSecondDerivativeManager ( ) const

Return the BC manager whose prescribed values are the second time derivative of the value-level BC, computed by one-sided three-point forward FD with step h = 1e-4 * max(1,|t|).

Rebuilt on each call from current value-level essentials, so late additions are reflected.

◆ setScalarBCs()

template<int spatial_dim, typename AppliedDisplacementFunction >

void smith::DirichletBoundaryConditions::setScalarBCs	(	const Domain &	domain,
		AppliedDisplacementFunction	applied_displacement
	)

inline

Specify time and space varying Dirichlet boundary conditions over a domain.

Parameters

domain	All dofs in this domain have boundary conditions applied to it.
applied_displacement	applied_displacement is a functor which takes time, and a smith::tensor<double,spatial_dim> corresponding to the spatial coordinate. The functor must return a double. For example: [](double t, smith::tensor<double, dim> X) { return 1.0; }
