ApplyEquiangular()

void stroid::topology::ApplyEquiangular

(

mfem::Vector &

pos

)

Apply an equiangular (gnomonic) projection to a point on a cube.

Parameters

pos	Position vector updated in-place.

ApplyKelvin()

void stroid::topology::ApplyKelvin	(	mfem::Vector &	pos,
		const fourdst::config::Config< config::MeshConfig > &	config )

Apply Kelvin transform outside the stellar radius.

Parameters

pos	Position vector updated in-place.
config	Mesh configuration (uses r_star and r_infinity).

ApplySpheroidal()

void stroid::topology::ApplySpheroidal	(	mfem::Vector &	pos,
		const fourdst::config::Config< config::MeshConfig > &	config )

Parameters

pos	Position vector updated in-place.
config	Mesh configuration (uses flattening).

BuildSkeleton()

std::unique_ptr< mfem::Mesh > stroid::topology::BuildSkeleton

(

const fourdst::config::Config< config::MeshConfig > &

config

)

Build the initial multi-block mesh topology for the star model.

Parameters

config

Mesh configuration (uses radii and domain flags).

Returns

Newly allocated mesh skeleton (not yet refined or curved).

Finalize()

void stroid::topology::Finalize	(	mfem::Mesh &	mesh,
