GASP: FAQ & Tips

Basic Execution of GASP

  • To run GASP's graphical user interface:
    • gasp
    • gasp --gui
    • gasp -i input_deck.gsp
  • To run GASP's flow solver (MPI auto launch):
    • gasp --solve -i input_deck.gsp
    • gasp -s -i input_deck.gsp
  • To run GASP's flow solver (MPI manual launch):
    • mpirun -np # gasp --mpi -i input_deck.gsp --run #
  • To show command line help:
    • gasp --help
    • gasp -h

Environment Variables

  • AEROSOFT_HOME specifies the aerosoft directory
  • GASP51_HOME specifies the aerosoft directory (supersedes AEROSOFT_HOME)

Stopping GASP Unexpectantly

  • If the file "stopgasp" exists, GASP will write the solution and stop the flow solver. The file "stopgasp" will be removed
  • If the file "writegasp" exists, GASP will write the solution and then continue the flow solver. The file "writegasp" will be removed
  • An easy way to create these files is using touch (ie. touch stopgasp)
