Discussion Overview

The discussion centers around finding a free and reliable FORTRAN compiler suitable for Computational Fluid Dynamics (CFD) applications. Participants share their experiences and recommendations regarding various compilers, including both free and paid options, while addressing issues related to installation and usability.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about free FORTRAN compilers for CFD, noting the difficulty in finding them compared to C++ compilers.
  • Another participant recommends gfortran as a standard free FORTRAN compiler based on their experience in a numerical analysis course.
  • A participant expresses frustration over the .bz file format encountered while downloading a compiler, seeking guidance on how to open it.
  • Another participant suggests using 7-zip to extract .bz2 files, providing a link to the software.
  • One user mentions downloading Plato, a FORTRAN 95 compiler, and expresses interest in checking out another compiler with 2003 updates.
  • A participant shares a link to g95, highlighting it as a free option without restrictions.
  • Discussion includes a mention of Intel's FORTRAN compiler, with one participant noting its high cost but good reputation.
  • A participant recommends Simply Fortran as a suitable option for Windows, discussing its paid service model and GUI features.
  • Another participant comments on the affordability of Simply Fortran, considering it reasonable compared to other software costs.
  • One participant reiterates the recommendation for g95, emphasizing its ease of use and ability to create standalone executable files.

Areas of Agreement / Disagreement

Participants generally agree on the utility of gfortran and g95 as free compilers, but there are differing opinions on the value of paid compilers like Simply Fortran and Intel's offering. The discussion remains unresolved regarding the best choice for specific needs.

Contextual Notes

Some participants express uncertainty about file formats and installation processes, indicating a need for clearer guidance on these technical aspects.

Hey PF, I'm looking for a free and reliable compiler for FORTRAN; the application will be for CFD. Unlike C++, FORTRAN compilers seem harder to find. If anyone can provide some insight besides "do a google search" that would be great, thanks.
 
Technology news on Phys.org
I've had a course on numerical analysis where we used fortran. A free compiler that they told us to get at home is gfortran. I think it may be the standard free fortran compiler.
 
I found that compiler after about 2 hours of searching. The download file is in .bz format of which I have no idea how to open.

I've done a quick google research, it seems that you can extract the .bz2 file using the program 7-zip (free, that you can download here: http://www.7-zip.org/).
 
I actually downloaded a compiler for FORTRAN 95, Plato. Ill probably check this one out too since it has 2003 updates. Thanks for the help.
 
You can look for compilers for your platform at The Fortran Company.

If you are Windows a nice choice I learned of lately is Simply Fortran. As we know, you cannot close open source or charge for free source, nevertheless, you may charge for the service of compiling it, collecting it, delivering it on media, making it easier to install...the way I see, the people at Simply Fortran are doing that and then some...they are also providing a GUI of their own. In any case, I think $25 is a reasonable fee; heck, some text editors may cost that much and they don't come with a Fortran compiler.

my 2 cents

gsal

P.S. ...no, I am not related to Simply Fortran in anyway

With a weekly budget of $100, $25 isn't cheap!

I just want to second the suggestion for g95. http://www.g95.org/downloads.shtml

- Free and without and "nags"

- Easy one file windows self extracting download. (g95-MiniGW.exe)

- Will create "stand alone" exe files (that run without needing extra libraries installed).

Definitely worth giving this one a try.
