Detailed Description

Interpolator class template.

This class template implements an interpolator which projects an (analytic) function into a Finite-Element space by evaluating its node functionals.

◆ project() [1/2]

template<typename DT_ , typename IT_ , typename Function_ , typename Space_ >
static void FEAT::Assembly::Interpolator::project ( LAFEM::DenseVector< DT_, IT_ > &  vector,
const Function_ &  function,
const Space_ &  space 
)
inlinestatic

Interpolates a scalar function.

Parameters
[out]vectorA transient reference to the vector that shall receive the interpolation coefficients. The vector is automatically allocated to the correct size, so it does not need to be allocated before calling this function.
[in]functionA transient reference to the function object implementing the Analytic::Function interface.
[in]spaceA transient reference to the Finite-Element space into which the function is to be projected.

◆ project() [2/2]

template<typename DT_ , typename IT_ , int block_size_, typename Function_ , typename Space_ >
static void FEAT::Assembly::Interpolator::project ( LAFEM::DenseVectorBlocked< DT_, IT_, block_size_ > &  vector,
const Function_ &  function,
const Space_ &  space 
)
inlinestatic

Interpolates a vector field.

Parameters
[out]vectorA transient reference to the vector that shall receive the interpolation coefficients. The vector is automatically allocated to the correct size, so it does not need to be allocated before calling this function.
[in]functionA transient reference to the function object implementing the Analytic::Function interface.
[in]spaceA transient reference to the Finite-Element space into which the function is to be projected.
