.. Planetary Removed Particles Jacob Kegerreis, 27th November 2020 .. _planetary_removed_particles: Removed Particles ================= If a particle leaves a non-periodic simulation box then it is removed. Currently, the particle's information is simply printed to stdout in a csv format (see ``hydro_remove_part()`` in ``src/hydro/Planetary/hydro.h``). This could be extracted for analysis e.g. using grep: ``grep '## Removed' -A 1 --no-group-separator output.txt > removed.txt``, then read e.g. with python: .. code-block:: python import numpy as np id, x, y, z, vx, vy, vz, mass, u, P, rho, h, mat_id, time = np.loadtxt( "removed.txt", delimiter=",", unpack=True ) pos = np.transpose([x, y, z]) vel = np.transpose([vx, vy, vz]) id = id.astype(int) mat_id = mat_id.astype(int)
