Detailed Description

pressure Poisson equation Solver

This class is the pressure Poisson equation Solver. It creats indices for all pressure points on the coarse and fine mesh, generates the matrix, and assigns the right hand side of the equation, then call PetscLinearSolver to solve the linear system.

Fields of pressure transform to 1d vector from the original two or three-dimensional domain. Solving pressure in vector form A x = b

pressure Poisson equation Solver

This class is the pressure Poisson equation Solver. It creats indices for all pressure points on the coarse and fine mesh, generates the matrix, and assigns the right hand side of the equation, then call PetscLinearSolver to solve the linear system.

Parameters:

numberOfPatches	number of patches
cellNumberPerPatch	cell numbers per patch surrounding the sphere
StartIndex	used to put the refined mesh
pointNumberMeshP	mesh points for p
dimension	dimension
xP	coordinates of p
h	space step
fp	extra force
exactPressure	exact pressure
pUnknowns	mesh points for p
p	pressure
pCagePoint	cage points for p
pSolver	PETSC linear solver
zeroInitialGuess	if use zero as the initial guess for pressure
