Class Documentation#

class PoissonSolverFFT2D : public PoissonSolver2D #

The PoissonSolverFFT2D class calculates electrostatic potential of a 2D charge distribution using 2D FFT approach.

Public Functions

PoissonSolverFFT2D(int xSize, int ySize)#: Constructor with sizes only

PoissonSolverFFT2D(int xSize, int ySize, double xMin, double xMax, double yMin, double yMax)#: Constructor wit sizes and limits

virtual ~PoissonSolverFFT2D()#: Destructor

virtual void setGridX(double xMin, double xMax)#: Sets x-grid. This method is virtual, because the setting of limits may involve some subclass specific actions.

virtual void setGridY(double yMin, double yMax)#: Sets y-grid. This method is virtual, because the setting of limits may involve some subclass specific actions.

virtual void setGridXY(double xMin, double xMax, double yMin, double yMax)#: Sets x-grid and y-grid simultaneously. This method is virtual, because the setting of limits may involve some subclass specific actions.

virtual void findPotential(Grid2D *rhoGrid, Grid2D *phiGrid)#: Solves the Poisson problem for an external charge distribution and puts results into an external potential grid
