This is an archive of the fixed-format Fortran programs provided by Joseph Katz and Allen Plotkin in their book titled Low-Speed Aerodynamics. The authors of the book reserve all rights to the code and these programs are transcribed verbatim for ease of use solely for educational purposes.
Each pXX directory contains a program.
Inside each directory, the source code is named pXX.f and an example output is provided with the name pXX.log.
A Makefile (tested on Linux) is also provided.
Compile the code using either the provided Makefile or using the command:
gfortran p14.f -o p14.outYou can then run it using
