Fill a user-provided grid function based on the underlying true vector.

This distributes true vector dofs to the finite element (local) dofs by multiplying the true dofs by the prolongation operator.

◆ gridFunction()

mfem::ParGridFunction & smith::FiniteElementState::gridFunction ( ) const

Construct a grid function from the finite element state true vector.

void smith::FiniteElementState::project ( const GeneralCoefficient & coef )

Projects a coefficient (vector or scalar) onto the field

◆ setFromFieldFunction()

template<typename FieldFunction >

void smith::FiniteElementState::setFromFieldFunction ( FieldFunction && field_function )

inline

Set state as interpolant of an analytical function.

In other words, this sets the dofs by direct evaluation of the analytical field at the nodal points.

Template Parameters

FieldFunction A callable type

Parameters

field_function A function that should have the signature: tensor<double, field_dim> field_function(tensor<double, spatial_dim> X)

template params: spatial_dim: number of components in the mesh coordinates field_dim: number of components of the FiniteElementState field

args: X: coordinates of the material point

returns: the value of the field at X.

If the field is scalar-valued, then alternatively the signature may be: double field_function(tensor<double, spatial_dim> X)

◆ setFromGridFunction()

void smith::FiniteElementState::setFromGridFunction ( const mfem::ParGridFunction & grid_function )
