 Temporal interval at which particles are to be released from a particle source (in s).\\  
 By default particles are released only at the beginning of a simulation (t_init=0). The time of the first release (t_init) can be changed with package parameter [#particle_advection_start particle_advection_start]. The time of the last release can be set with the package parameter [#end_time_prel end_time_prel]. If '''dt_prel''' has been set, additional releases will be at ''t = t_init+'''dt_prel''', t_init+2*'''dt_prel''', t_init+3*'''dt_prel''', etc..'' Actual release times may slightly deviate from thesel values (see e.g. [../d3par#dt_dopr dt_dopr]).\\\\

 The output of particles for visualization with the graphic software '''dvrp''' is steered by the package parameter [../dvrpar#dt_dvrp dt_dvrp]. For visualization purposes particles can be given a diameter using the parameters [../dvrpar#dvrp_psize dvrp_psize] and [../dvrpar#particle_dvrpsize particle_dvrpsize] (this diameter only affects the visualization). All particles have the same size. Alternatively, particles can be given an individual size and a color by modifying the user-interface ''(subroutine user_init_particles)''. Particles can pull a ''tail'' behind themselves to improve their visualization. This is steered via the parameter [#use_particle_tails use_particle_tails].\\\\

 Lateral boundary condition (x-direction) for particle transport. \\
 By default, cyclic boundary conditions are used along x. Alternatively, reflection ('''bc_par_lr''' = '' 'reflect' '') or absorption ('''bc_par_lr''' = '' 'absorb' '') can be set. \\
 This lateral boundary conditions should correspond to the lateral boundary condition used for the flow (see [../inipar#bc_lr bc_lr]).
