Hello,
To answer your question about the FORTRAN compiler, it is always recommended that you use TELEMAC without having to modify its sources -- in which case you do not need a FORTRAN compiler.
If you wish to modify the source code and implement your own subroutine for a specific application, you should probably then think of finding a Fortran compiler. You can buy the Intel Fortran Compiler for Windows from the majority of software vendors. Alternatively, you can download the g95 Fortran Compiler for Windows (
The G95 Project), which is free.
Please note that we are mentioning these two names to help your search for a Fortran compiler but we do not mean to endorse any compiler in particular.
TELEMAC being developed under strict standard Fortran rules, it remains independent of the compiler you choose, and independent of the Operating System you use (windows, Linux, Unix, etc.)
Hope this helps.
Sébastien.
