The archive file vlmd.zip contains the files:

lar15160.txt the original COSMIC description of the program
readme.txt general information
read.me extra input information supplied by Raj Nangia
input.txt instructions for use of VLMD
geom.for the source code for geometry
analysis.for the source code for analysis
case1.inp input data for test case 1
case1.out combined output from geom and analysis for this test case.
case2.inp input data for test case 2
case2.out combined output from geom and analysis for this test case.
case3.inp input data for test case 3
case3.out combined output from geom and analysis for this test case.
case4.inp input data for test case 4
case4.out combined output from geom and analysis for this test case.

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 vlmdexecs.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.
