Detailed Description

template<int FIELD_ID = -1>
class mfem::future::FieldOperator< FIELD_ID >

Base class for FieldOperators.

This class serves as a base for different FieldOperator types which can be applied to fields that are used with inputs to a quadrature point function. See DifferentialOperator.

Constructor & Destructor Documentation

FieldOperator()

template<int FIELD_ID = -1>

mfem::future::FieldOperator< FIELD_ID >::FieldOperator ( int size_on_qp = 0 )

inlineconstexpr

Constructor for the FieldOperator.

This constructor initializes the FieldOperator with it's size on quadrature points. The size on quadrature points has to be determined by the FieldOperator type, the dimension and the vector dimension (number of components). See the following examples

Scalar FiniteElementSpace with Value FieldOperator: size = vdim x dim x 1 = 1 x dim x 1 = dim

Vector FiniteElementSpace with Gradient FieldOperator: size = vdim x dim x dim = vdim x dim x dim = vdim * dim^2

ParameterSpace with Identity FieldOperator: size = vdim = vdim
