Danke Diego,
sehr interessant was es alles an älterer freier Software gibt.
Viel Glück und Gesundheit im Jahr 2021!

Caro Hans, questi linguaggi hanno generato una grande quantità di codice utilizzato nel mondo (vedi ad esempio http://fortranwiki.org/fortran/show/libraries o https://cug.org/5-publications/proceedings_attendee_lists/2003CD/S03_Proceedings/Pages/Authors/Hribar/Hribar.htm); accanto al nuovo resta quindi "il vecchio" sempre rilucidato. Questo però è possibile solo perchè tutto questo e disponibile per tutti in codice sorgente.

Saluti da Bozen,

Hallo Diego,
obwohl ich mich ausgiebig mit Fluiddynamik befasst habe, ist XFOIL doch zu komplex, als dass ich es mir zum herumprobieren installiere werde. Es ist aber schon erstaunlich, dass ein ursprünglich in FORTRAN geschriebenes Programm heute noch viel verwendet wird.

Ciao Hans.
Mi sono velocemente guardato il README del pacchetto xfoil6.99.tgz (disponibile in forma sorgente in Fortran f77 o g77)  dove leggo:

General
-------
XFOIL and its plot library should compile on any Unix system
with normal Fortran-77, C, and X-Windows support.  So far,
XFOIL has been tested on the following systems:

  DEC-5000
  Alpha
  SGI
* Sun
* RS/6000
* HP-9000
* Pentium/Linux 

Questo programma quindi, con le attenzioni del caso indicate nella documentazione, risulta compilabile sotto Linux.

Il programma di plot é dato per win32, ma credo sia possibile con i sorgenti F77 in mano utilizzare gplot (per Linux) 
=> installando pgplot5 - large subroutine library for plotting scientific data

Hallo Liste,
es gibt auch sehr komplexe Programme welche opensource sind:
Allerdings nicht unter Linux lauffähig.
