◆ generate_radial_particles()

fv-tracers-radial-jet.generate_radial_particles	(	file_path,
		num_rays = 20,
		particles_per_ray = 50,
		r_min = 0.05,
		r_max = 1.0,
		center_x = 1.5,
		center_y = 1.5 )

Generates a .dat file with particles arranged radially from the domain center.

Parameters: file_path (str): Path to save the .dat file. num_rays (int): Number of angular directions (rays). particles_per_ray (int): Number of particles along each ray. r_min (float): Minimum distance from center (to avoid singularity). r_max (float): Maximum distance from center. center_x (float): X-coordinate of the radial center. center_y (float): Y-coordinate of the radial center.
