Changes of Transport Calculation Mode
The transport calculations mode names are changed.
The non-magnetic RTA and ITA modes correspond to
calc_mode = 'trans-rta'and
calc_mode = 'trans-ita'respectively.
Magnetic RTA and ITA correspond to
calc_mode = 'trans-mag-rta'and
calc_mode = 'trans-mag-ita'.
The boltz_nstep parameter is set to zero by default only for the non-magnetic RTA calculation and set to 50 by default for other transport calculation modes. The user can change the boltz_nstep value from the input file.
All the data that outputs to ASCII text files, is now also written in YAML files (the text output being fully preserved). The YAML files can be easily postprocessed with Python using the PyYAML package.
Change of prefix_tdf.h5 format
The format HDF5 output file of the trans calculation mode (prefix_tdf.h5) was changed and made more userfriendly. Each line from the temper file now correspond to a separate group (called
configuration). Inside each group there might be the
iterations subgroup if the transport calculation was iterative.
