Detailed Description

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

A product of sinusoids \(u(\boldsymbol{x}) = \prod_i \sin(k_i x_i)\).

Details

Solves the Poisson equation \(-\Delta u(x)=f(x)\) for a source \(f(x)=\boldsymbol{k}^2\prod_i \sin(k_i x_i)\).

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.
