Last change on this file since 27 was 27, checked in by hasod, 7 years ago
  • Implemented optional namelist input for COMMAND, RELEASES, SPECIES, AGECLASSES,OUTGRID,OUTGRID_NEST,RECEPTORS
  • Implemented com_mod switch nmlout to write input files as namelist to the output directory (.true. by default)
  • Proposed updated startup and runtime output (may change back to previous info if desired)
  • Property svn:executable set to *
