---|
52 | ! 2630 2017-11-20 12:58:20Z schwenkel |
---|
53 | ! Enabled particle advection with grid stretching. Furthermore, the CFL- |
---|
54 | ! criterion is checked for every particle at every time step. |
---|
55 | ! |
---|
56 | ! 2606 2017-11-10 10:36:31Z schwenkel |
---|
57 | ! Changed particle box locations: center of particle box now coincides |
---|
58 | ! with scalar grid point of same index. |
---|
59 | ! lpm_move_particle now moves inner particles that would leave the core |
---|
60 | ! to the respective boundary gridbox. Afterwards they get transferred by |
---|
61 | ! lpm_exchange_horiz. This allows particles to move more than one gridbox |
---|
62 | ! independent of domain composition. |
---|
63 | ! Renamed module and subroutines: lpm_pack_arrays_mod -> lpm_pack_and_sort_mod |
---|
64 | ! lpm_pack_all_arrays -> lpm_sort_in_subboxes, lpm_pack_arrays -> lpm_pack |
