Generating an IC Data File

Procedure

1. Use PuTTY to log in to the server as the root user.
2. Go to the main program installation directory.

   cd /path/to/POM

3. Move the POM2K and GRID-DATA directories to the installation directory of the main program (other files can be deleted).

   cd www.ccpo.odu.edu/POMWEB/
   mv POM2K ../../
   mv GRID-DATA ../../

4. Go to the directory where the GRID-DATA test case is stored.

   cd /path/to/POM/GRID-DATA

5. Create the IC and include directories.

   mkdir IC
   mkdir -p /path/to/POM/GRID-DATA/IC/include

6. Copy the header files gridborder, gridcom, and params to the include directory.

   cp gridborder /path/to/POM/GRID-DATA/IC/include
   cp gridcom /path/to/POM/GRID-DATA/IC/include
   cp params /path/to/POM/GRID-DATA/IC/include

7. Modify the rungrid file.
   1. Open the rungrid file.

      vi rungrid

   2. Press i to enter the edit mode and modify the file as follows:

      Before the modification:

      echo ' Start Compiling ...'
      g77 -O3 GRID.f
      #pgf77 GRID.f
      a.out > printout
      #
      # -------------- output files for POM2K ------------------------
      /bin/mv fort.40 IC.dat # formatted IC,grid & constant wind
      # -------------- output files for MATLAB plotting -------------
      /bin/mv fort.43 ijk.dat # IM, JM, KB, Z
      /bin/mv fort.44 plt.dat # formatted grid
      /bin/mv fort.45 bnd.dat # boundary points (gridborder)
      /bin/mv fort.46 wnd.dat # wind velocity
      /bin/mv fort.47 dxy.dat # dx,dx (km)
      #
      /bin/rm a.out
      /bin/rm fort.*
      echo ' *** END GRID ***'

      After the modification:

      echo ' Start Compiling ...'
      flang -O3 GRID.f -I/path/to/POM/GRID-DATA/IC/include
      #pgf77 GRID.f
      #./a.out > printout
      #
      # -------------- output files for POM2K ------------------------
      #mv fort.40 IC.dat # formatted IC,grid & constant wind
      # -------------- output files for MATLAB plotting -------------
      #mv fort.43 ijk.dat # IM, JM, KB, Z
      #mv fort.44 plt.dat # formatted grid
      #mv fort.45 bnd.dat # boundary points (gridborder)
      #mv fort.46 wnd.dat # wind velocity
      #mv fort.47 dxy.dat # dx,dx (km)
      #
      #/bin/rm a.out
      #/bin/rm fort.*
      echo ' *** END GRID ***'

   3. Press Esc, type :wq!, and press Enter to save the file and exit.
8. Copy the data files to the IC directory.

   cp /path/to/POM/GRID-DATA/TOPO.dat /path/to/POM/GRID-DATA/IC
   cp /path/to/POM/GRID-DATA/TS.dat /path/to/POM/GRID-DATA/IC
   cp /path/to/POM/GRID-DATA/WIND.dat /path/to/POM/GRID-DATA/IC
   cp /path/to/POM/GRID-DATA/GRID.f /path/to/POM/GRID-DATA/IC
   cp /path/to/POM/GRID-DATA/IC.dat /path/to/POM/GRID-DATA/IC

9. Set the environment variables.

   export CC=mpicc
   export CXX=mpicxx
   export FC=mpif90

10. Grant the permission to rungrid and execute it.

    chmod 755 rungrid
    ./rungrid
