Detailed Description

Generates Domain objects form a given p4est object.

Member Typedef Documentation

using ThunderEgg::P4estDomainGenerator::BlockMapFunc = std::function<void(int block_no, double unit_x, double unit_y, double& x, double& y)>

Maps coordinate in a block to a coordinate in the domain.

Each block is treated as a unit square. The input wil be the block number and a coordinate withing that unit square.

Parameters

block_no	the block number
unit_x	the x coordinate in the block
unit_y	the y coordinate in the block
x	the resulting x coordinate of the mapping function
y	the resulting y coordinate of the mapping function

ThunderEgg::P4estDomainGenerator::P4estDomainGenerator	(	p4est_t *	p4est,
		const std::array< int, 2 > &	ns,
		int	num_ghost_cells,
		const BlockMapFunc &	bmf
	)

Construct a new P4estDomainGenerator object.

Parameters

p4est	the p4est object
ns	the number of cells in each direction
num_ghost_cells	the number of ghost cells on each side of the patch
bmf	the function used to map the blocks to the domain
