This Fortran code explores the Fermi–Pasta–Ulam–Tsingou(FPUT) problem in chaos theory by simulating a 1D chain with non-linear dynamics with symplectic integrators.
To build the Fortran code, run:
meson setup build
ninja -C build/
and the binary will reside at build/fput. Python code in pysrc is mainly for
plotting, and its main function resides in plot.py.
The programs all read and write to stdin/stdout; Make use of pipes in shell to redirect to and from files.
