Detailed Description

template<typename ValueTypeOperator, typename ValueTypeOperand, utils::MemorySpace memorySpace, size_type dim>
class dftefe::electrostatics::PoissonLinearSolverFunctionFE< ValueTypeOperator, ValueTypeOperand, memorySpace, dim >

A derived class of linearAlgebra::LinearSolverFunction to encapsulate the Poisson partial differential equation (PDE) discretized in a finite element (FE) basis. The Possion PDE is given as: $\nabla^2 v(\textbf{r}) = -4 \pi \rho(\textbf{r})$\f with the boundary condition on $@_fakenlv(\textbf{r})|_{\partial \Omega}=g(\textbf{r})$\f ( $\\partial Omega$\f denoting the boundary of a domain $\Omega$\f). Here $v$\f has the physical notion of a potential (e.g., Hartree potential, nuclear potential, etc.) arising due to a charge distributin $\rho$\f.

Template Parameters

ValueTypeOperator	The datatype (float, double, complex<double>, etc.) for the underlying operator
ValueTypeOperand	The datatype (float, double, complex<double>, etc.) of the vector, matrices, etc. on which the operator will act
memorySpace	The meory sapce (HOST, DEVICE, HOST_PINNES, etc.) in which the data of the operator and its operands reside
dim	Dimension of the Poisson problem
