Post Processing Particle Traces ################################### This option enables the calculation of particle trajectories and computed quantities along the trajectories. The coordinates of the trajectory starting point and time-stepping parameters are input using the cards in this section. The computation of quantities along the trajectories and their subsequent output is controlled through the *usr_ptracking* routine in user_post.c. .. include:: post_processing_particle/post_processing_particle_traces.rst .. include:: post_processing_particle/particle.rst .. include:: post_processing_particle/end_of_particles.rst
