    1371 Optimization of collision kernels. Collision efficiency tables can be calculated once at simulation start for defined radius (and dissipation) classes instead of re-calculating them at every time step and for the particle ensemble in every grid box (see [../../app/parpar#collision_kernel collision_kernel] = '' 'hall_fast' '' or '' 'wang_fast' ''). For this purpose the particle feature 'color' is renamed 'class'. New parpar-parameters [../../app/parpar#radius_classes radius_classes] and [../../app/parpar#dissipation_classes dissipation_classes] are introduced in order to define the resolution of the collision table. The optimized kernels speed-up simulations significantly. (Makefile, advec_particles, check_parameters, data_output_dvrp, header, init_particles, lpm_collision_kernels, modules, package_parin, set_particle_attributes)

    13731373Lower limit for droplet radius changed from 1.0E-7 to 1.0E-8. (advec_particles)
     
    14551455Particle attributes speed_x|y|z_sgs renamed rvar1|2|3. This is required because these attributes are now used for two different applications (i.e. the SGS-velocity model and the Rosenbrock method for integrating the droplet growth equation). (advec_particles, data_output_ptseries, modules, init_particles, particle_boundary_conds)
    14561456
    1457 Routine wang_kernel and respective module renamed lpm_collision_kernels. Package (particle) parameters {{{wang_collision_kernel}}} and {{{turbulence_effects_on_collision}}} replaced by new particle-parameter [../../app/parpar/#collision_kernel collision_kernel]. (Makefile, advec_particles, check_parameters, diffusion_e, init_3d_model, modules, package_parin, time_integration, '''new:''' lpm_collision_kernels, '''removed:''' wang_kernel)
