 Thank you very much

 There are various solutions to install gfortran (or in general the GCC compiler suite) on Windows: Cygwin and MinGW-w64/MSYS2 are both environments that mimick to a certain extent Linux and allow you to manage all manner of packages, among which the GCC compiler suite. I use both but I also use the installation from equation.com - http://www.equation.com/servlet/equation.cmd?fa=fortran. You can get Intel Fortran oneAPI from Intel - https://www.intel.com/content/www/us/en/developer/tools/oneapi/fortran-compiler.html#gs.xy9u8f. 

General questions about Fortran: the comp.lang.fortran newsgroup or, a bit more modern, Fortran discourse - https://fortran-lang.discourse.group/

The gfortran compiler and the Intel Fortran oneAPI compiler, both freely available, would easily handle such arrays as you mention. What system are you running on?

Hello,

I am an engineer for the nuclear power industry.  As part of my master’s thesis I developed a model of a fuel pin using Fortran.  At the time I was working with a cheap Microsoft compiler.  It was version 5.1 if I remember correctly.  My model does 3D finite differencing and is rather demanding on the compiler.  My Microsoft compiler was pretty limiting on the size of the modules I could compile.  Typically I was working with a 7x7x7 spatial array with a 5 properties at each node.  Everything was in double precision.  So it was 7x7x7x5.  I could juggle these around, but I had to say within this maximum or the compiler would not work.  I would like to work with MUCH larger arrays.  I am thinking 100x100x100x5.  Again in double precision. So I need a better compiler.  Can you help?

Regards,

Bill Carter
