Generate a ELA-class object.

Source: R/create_scatterer.R

Generate a ELA-class object.

Usage

ela_generate(
  shape,
  density_body = NULL,
  sound_speed_longitudinal_body = NULL,
  sound_speed_transversal_body = NULL,
  theta_body = pi/2,
  ID = NULL,
  length_units = "m",
  theta_units = "radians"
)

Arguments

shape

Pre-built Shape object describing the elastic target geometry.

density_body

Optional body density (kg/m^3).

sound_speed_longitudinal_body

Optional longitudinal wave speed (m/s).

sound_speed_transversal_body

Optional transversal wave speed (m/s).

theta_body

Body orientation relative to the incident wave (radians).

ID

Optional metadata identifier.

length_units

Compatibility argument. Scatterer constructors now assume meters and ignore non-SI alternatives.

theta_units

Compatibility argument. Scatterer constructors now assume radians and ignore non-SI alternatives.

Value

ELA-class object.

Details

ela_generate() builds a generic solid-elastic scatterer under the shared ELA class. Unlike CAL, it is not restricted to spheres, so it can carry prolate, oblate, cylindrical, or arbitrary elastic shapes together with the body density and longitudinal/transversal wave speeds used by solid-elastic models such as TMM.
