Detailed Description

The code below is an example of a complete specification of a groupset.

--===================================== Setup physics

chiSolverAddRegion(phys1,region1)
 
chiLBSSetProperty(phys1,DISCRETIZATION_METHOD,PWLD3D)
chiLBSSetProperty(phys1,SCATTERING_ORDER,1)
 
--========== Groups

cur_gs = gs0
chiLBSGroupsetAddGroups(phys1,cur_gs,0,15)
chiLBSGroupsetSetQuadrature(phys1,cur_gs,pquad0)

chiLBSGroupsetSetResidualTolerance(phys1,cur_gs,1.0e-4)
chiLBSGroupsetSetMaxIterations(phys1,cur_gs,300)
chiLBSGroupsetSetGMRESRestartIntvl(phys1,cur_gs,30)
chiLBSGroupsetSetWGDSA(phys1,cur_gs,30,1.0e-4,false," ")
chiLBSGroupsetSetTGDSA(phys1,cur_gs,30,1.0e-4,false," ")

Groupsets segregate the code into pieces arranged by the number of groups it contains. A great deal of care must be taken with intergroupset transfer since the order in which the groupsets are executed determine what information will be available to them.

chiLBSGroupsetSetAngleAggDiv()

void chi_lua::chiLBSGroupsetSetAngleAggDiv	(	int	SolverIndex,
		int	GroupsetIndex,
		int	NumDiv
	)

Sets the angle aggregation divisions

Parameters

SolverIndex	int Handle to the solver for which the group is to be created.
GroupsetIndex	int Handle to the groupset to which the group is to be added.
NumDiv	int Number of divisions to use for the angle aggregation.

Note: by default polar aggregation will combine all polar angles in a hemisphere for a given azimuthal angleset. Therefore if there are 24 polar angles and 4 azimuthal angles the default polar aggregation will create 8 anglesets (2 per quadrant to allow top and bottom hemisphere) and each angleset will have the 12 polar angles associated with a hemisphere. When the number of divisions is greater than 1 then the polar angles will be split into divisions. For example if the number of divisions is 2 then more angleset will be created, this time having 6 polar angles per angleset.

chiLBSGroupsetSetAngleAggDiv(phys1,cur_gs,1)

Notes on selecting iterative methods

The iterative methods NPT_CLASSICRICHARDSON, NPT_CLASSICRICHARDSON_CYCLES, NPT_GMRES and NPT_GMRES_CYCLES are considered legacy. The NPT_GMRES and NPT_GMRES_CYCLES are now considered deprecated with the inclusion of the generalized Krylov iteration method-class (which supports all the options prepended with KRYLOV_).

RICHARDSON is probably the least memory consuming but has the poorest convergence rate.

GMRES generally has the best convergence rate but it builds a basis comprising multiple solutions vectors, the amount of which is controlled via the gmres-restart parameter, which can dramatically increase memory consumption. GMRES restarts, i.e. the amount of iterations before the basis is destroyed and restarted, influences both memory consumptions and convergence behavior, e.g., lower restart numbers generally lowers memory consumption but increases the amount of iteration required to convergence.

The required memory and the computational time for one iteration with BiCGStab is constant, i.e., the time and memory requirements do not increase with the number of iterations as they do for restarted GMRES. BiCGStab uses approximately the same amount of memory as GMRES uses for two iterations. Therefore, BiCGStab typically uses less memory than GMRES. The convergence behavior of BiCGStab is often more irregular than that of GMRES. Intermediate residuals can even be orders of magnitude larger than the initial residual, which can affect the numerical accuracy as well as the rate of convergence. If the algorithm detects poor accuracy in the residual or the risk of stagnation, it restarts the iterations with the current solution as the initial guess. In contrast to GMRES, BiCGStab uses two matrix-vector multiplications each iteration (requiring two transport sweeps). Also, when using the left-preconditioned BiCGStab, an additional preconditioning step is required each iteration. That is, left-preconditioned BiCGStab requires a total of three preconditioning steps in each iteration. We generally apply Within-group Diffusion Synthetic Acceleration (WGDSA) and Two-Grid Acceleration (TGDSA) as left-preconditioners and therefore the total cost of these pre-conditioners will increase when using BiCGStab. Use BiCGStab when you are running problem with a high scattering order (i.e., L is large) because this will dramatically increase the GMRES basis.
