Function Documentation

compute_tangential_vector()

AMREX_GPU_HOST_DEVICE AMREX_FORCE_INLINE vs::Vector amr_wind::actuator::utils::compute_tangential_vector	(	const vs::Vector &	center,
		const vs::Vector &	normal,
		const vs::Vector &	point )

delta_pnts_cyl()

AMREX_GPU_HOST_DEVICE AMREX_FORCE_INLINE vs::Vector amr_wind::actuator::utils::delta_pnts_cyl	(	const vs::Vector &	origin,
		const vs::Vector &	normal,
		const vs::Vector &	point1,
		const vs::Vector &	point2 )

Compute distance between two points

Parameters

origin	Origin for the cylindrical coordinate system
normal	Normal relative to origin (defines cylinder orientation)
point1	location of the first point in Cartesian coordinates
point2	location of second point in Cartesian coordinates

Returns

distance between points in cylindrical coordinates (angle is in radians)

determine_influenced_procs()

std::set< int > amr_wind::actuator::utils::determine_influenced_procs	(	const amrex::AmrCore &	mesh,
		const amrex::RealBox &	rbx )

Return a set of process IDs (MPI ranks) that contain AMR boxes that interact with a given actuator body.

The region of influence of the actuator body is determined by checking for intersections with a bounding box rbox.

Parameters

mesh	AMReX mesh instance
rbx	The bounding box that defines the region of influence of a turbine

determine_root_proc()

void amr_wind::actuator::utils::determine_root_proc	(	ActInfo &	info,
		amrex::Vector< int > &	act_proc_count )

gaussian1d()

AMREX_GPU_DEVICE AMREX_FORCE_INLINE amrex::Real amr_wind::actuator::utils::gaussian1d	(	const amrex::Real &	dist,
		const amrex::Real &	eps )

Return the Gaussian smearing factor in 1D

Parameters

dist	Distance vector of the cell center from the actuator node in local frame of reference.
eps	One-dimensional Gaussian scaling factor

Returns

Gaussian smearing factor in 1D

gaussian3d()

AMREX_GPU_DEVICE AMREX_FORCE_INLINE amrex::Real amr_wind::actuator::utils::gaussian3d	(	const vs::Vector &	dist,
		const vs::Vector &	eps )

Return the Gaussian smearing factor in 3D

Parameters

dist	Distance vector of the cell center from the actuator node in local frame of reference.
eps	Three-dimensional Gaussian scaling factor

Returns

Gaussian smearing factor in 3D

		const amrex::Real	dX )

Compute weighting for a normalized linear interpolant

Parameters

distance	distance between sample location and the reference points
dX	spacing between reference points

Returns

normalized integration weight at the sample location

prepare_netcdf_file()

void amr_wind::actuator::utils::prepare_netcdf_file	(	const std::string &	ncfile,
		const TurbineBaseData &	meta,
		const TurbineInfo &	info,
		const ActGrid &	grid )

read_inputs()

void amr_wind::actuator::utils::read_inputs	(	TurbineBaseData &	tdata,
