To compile this program for your computer, use the commands
gfortran geom.f90 -o geom.exe gfortran analysis.for -o analysis.exe
Linux and Macintosh users may prefer to omit the .exe on the file name.
To run this pair of programs, one first enters the command
geom
The geom program asks for the name of the input file. This must be a file written to conform to the instructions in the NASA TN. Geom produces a file called geom.out and a specially formatted file called FORT25. FORT25 is not designed to be read or printed; it is the input to Analysis. To launch the analysis program, enter the command
analysis
When Analysis is launched, it asks no questions, but takes the file called FORT25 and completes the remainder of the calculations. This produces a file called analysis.out that is designed to be printed.
It is best if you compile the programs using your Fortran compiler with the appropriate options for your computer system. If you are unable or do not wish to do this, you may download vlmdexec.zip containing the files geom.exe, geom.mac, and geom.lnx, the geom executable program for Windows, Mac OS X, and Linux, each compiled generically for an Intel CPU. Similarly, it contains analysis.exe, analysis.mac, and analysis.lnx.
