getMAC is a program that reads the definition of a wing from an arbitrary number of chords. The instructions for preparing an input file for getMAC are in the file getmac.txt. The program reads the input file and prints the area, length of MAC, y of MAC, xle of MAC, xte of MAC, and x of c/4 of MAC.
To compile this program for your machine, use the command
gfortran getmac.f90 -o getmac.exe
Linux and Macintosh users may prefer to omit the .exe on the file name.
Launch the program by typing getmac.exe at the command line. The program will ask you for the name of the input data file. After reading the input data, the program produces getmac.out with the computed results.
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 getmacexecs.zip containing the files getmac.exe, getmac.mac, and getmac.lnx, the executable programs for Windows, Mac OS X, and Linux, each compiled generically for an Intel CPU.
