Thank you very much On Monday, April 25, 2022, 08:13:44 AM CDT, Arjen Markus <arjen.markus...@gmail.com> wrote: 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.

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?

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 Sent from Mail for Windows
