Generate a CAL-class object.

Generate a CAL-class object.

Usage

cal_generate(
  material = "WC",
  diameter = 0.0381,
  sound_speed_longitudinal = NULL,
  sound_speed_transversal = NULL,
  density_sphere = NULL,
  theta_sphere = pi,
  ID = NULL,
  diameter_units = "m",
  theta_units = "radians",
  n_segments = 100
)

Arguments

material

Material-type for the soldi sphere. See 'Details' built-in material options.

diameter

Spherical diameter (m).

sound_speed_longitudinal

Longitudinal sound speed (m/s).

sound_speed_transversal

Transversal sound speed (m/s).

density_sphere

Density (kg/m^3).

theta_sphere

Backscattering direction (Default: pi radians).

ID

Optional metadata ID input.

diameter_units

Compatibility argument. cal_generate() now assumes meters and ignores non-SI alternatives.

theta_units

Compatibility argument. cal_generate() now assumes radians and ignores non-SI alternatives.

n_segments

Number of segments to discretize object shape.

Value

Generates a CAL-class object.

Details

There are several options for the material argument:

Material	Argument	c1	c2	\(\rho1\)	Tungsten carbide
"WC"	6853	4171	14900	Stainless steel	"steel"
5980	3297	7970	Brass	"brass"	4372
2100	8360	Copper	"Cu"	4760	2288.5
8947	Aluminum	"Al"	6260	3080	2700
