Detailed Description

template<size_t Dim, typename DataType = DataVector>
class Poisson::Solutions::ProductOfSinusoids< Dim, DataType >

A product of sinusoids $u (x) = \prod_{i} \sin (k_{i} x_{i})$ .

Details

Solves the Poisson equation $- Δ u (x) = f (x)$ for a source $f (x) = k^{2} \prod_{i} \sin (k_{i} x_{i})$ .

If DataType is ComplexDataVector, the solution is multiplied by exp(i * complex_phase) to rotate it in the complex plane. This allows to use this solution for the complex Poisson equation.
