The archive file cas2d.zip contains the files:
|lew13854.txt||the program description from COSMIC|
|original.src||the original copy of the source code (from COSMIC)|
|cas2d.f||the complete source code in modern Fortran|
To compile this program for your machine, use the command:
gfortran cas2d.f90 -o cas2d.exe
Linux and Macintosh users may prefer to omit the .exe on the file name.
To launch the program, enter "cas2d" at the command line. This old program uses a legacy style of assuming the input is from standard input and output to standard output.
cas2d < mycase.inp ^gt; mycase.out
There seems to some residual problem with this code. Even though it runs and produces satisfactory answers, it always gives warnings of invalid floating point operations, namely a denormal flag. I will continue to investigate, but I want to release it because some of you may well be better at diagnostics than I am.
