template<typename TrialExpression, typename TestExpression, typename Support = InferredIntegrationSupport>
class WeakTerm

A solver-neutral FE weak term contributed to a residual row.

inline const Support &integration_support() const

inline WeakTerm with_cached_assembly() const

Retain a linear pairing after its first assembly.

Meshes, mappings, lifted reference geometry, integration support, FE spaces and homogeneous constraint coefficients must stay fixed while this term is used. State values and affine constraint offsets may change. Rebuild the term after changing any fixed data. Nonlinear trials are rejected; the default keeps assembling the current pairing on demand.

template<typename VectorType, typename MatrixType>
inline FieldId add(SemidiscreteBuilder<VectorType, MatrixType> &builder) const

template<typename VectorType, typename MatrixType>
inline void add_constraint_terms(SemidiscreteBuilder<VectorType, MatrixType> &builder, const FieldId multiplier, const double sign, const std::size_t index) const

Add both rows of this term to a multiplier constraint.

template<typename VectorType, typename MatrixType>
inline FieldId operator()(SemidiscreteBuilder<VectorType, MatrixType> &builder) const

template<typename Callback>
inline WeakTerm with_context_update(Callback callback) const

Return this term with a callback run before each evaluation context.
