new_sphericalmassencl_sphere

amuse_util.ic.invcdf.new_sphericalmassencl_sphere(number_of_particles: int, encl_mass_func: function, vel_potential, \*list_arguments, \*\*keyword_arguments)

Create a sphere with the given number of particles.

Returns a set of stars with equal mass and positions and velocities distributed to fit an enclosed mass function. The model is centered around the origin. Positions and velocities are optionally scaled such that the kinetic and potential energies are 0.25 and -0.5 in nbody-units, respectively.

Parameters

number_of_particles: int

Number of particles to include in the plummer sphere

encl_mass_func: function

vel_potential: amuse potential

convert_nbody: When given will convert the resulting set to SI units

radius_cutoff: Cutoff value for the radius (defaults to 22.8042468)

mass_cutoff: Mass percentage inside radius of 1

do_scale: scale the result to exact nbody units (M=1, K=0.25, U=-0.5)
