Detailed Description

Refine Domain1D grids so that profiles satisfy adaptation tolerances.

Definition at line 16 of file refine.h.

Member Function Documentation

setCriteria()

void setCriteria	(	doublereal	ratio = 10.0,
		doublereal	slope = 0.8,
		doublereal	curve = 0.8,
		doublereal	prune = -0.1
	)

Set grid refinement criteria.

Parameters

ratio	Maximum ratio between grid spacing at adjacent intervals. E.g. (x[j+1] - x[j]) / (x[j] - x[j-1]) < ratio
slope	Maximum fractional change in the value of each solution component between adjacent grid points
curve	Maximum fractional change in the derivative of each solution component between adjacent grid points.
prune	Threshold for removing unnecessary grid points. prune should be smaller than both slope and curve. Set prune <= 0 to disable pruning.
