Has anyone used Dolfyn ? It too is free, and looks as if it has an extremely simple interface.
When I unzip the file and try and istall the program, I get several 'F90' files.
What is an 'F90' file ? I looked up what an 'F90' file is, and apparently is is for Macs and something called a flotran compiler ( or something like that ).
I'm pretty sure I downloaded the Windows version, but perhaps not ?
