Detailed Description

Splits a mesh part into many.

usually the construction of a specific Splitter will ask for a mesh object, which is the part to be acted upon

Member Function Documentation

virtual Migration* apf::Splitter::split	(	MeshTag *	weights,
		double	tolerance,
		int	multiple
	)			`[pure virtual]`

call the underlying split algorithm

Parameters:

	weights	a tag of one double that should be attached to all the elements. splitters will try to balance the total element weight of the resulting parts. Some splitters support a weights pointer of zero, in which case elements are weighted equally
	tolerance	a factor greater than one at such that if max_weight < tolerance * average_weight the splitter will consider the parts balanced
	multiple	how many output parts to generate

Returns:: a migration object mapping all elements in the local part to part ids from 0 to multiple - 1. some splitters have convenience options that will change the resulting part ids.
