ScalarParameter

BoundaryNormalComponent

PrioritizedSubexpression
When the optemplate-to-code transformation is performed, prioritized subexpressions work like common subexpression in that they are assigned their own separate identifier/register location.

Operator

StatelessOperator

OperatorBinding

DiffOperatorBase

DifferentiationOperator

MInvSTOperator

StiffnessOperator

StiffnessTOperator

MassOperatorBase

MassOperator

InverseMassOperator

ElementwiseMaxOperator

BoundarizeOperator

FluxExchangeOperator
An operator that results in the sending and receiving of boundary information for its argument fields.

BoundaryPair
Represents a pairing of a volume and a boundary field, used for the application of boundary fluxes.

FluxOperatorBase

FluxOperator

LiftingFluxOperator

VectorFluxOperator

LocalOpReducerMixin
Reduces calls to mapper methods for all local differentiation operators to a single mapper method, and likewise for mass operators.

FluxOpReducerMixin
Reduces calls to mapper methods for all flux operators to a smaller number of mapper methods.

OperatorReducerMixin
Reduces calls to *any* operator mapping function to just one.
