Code generator for [[https://github.com/boutproject/BOUT-dev/][BOUT++]] in python. Example:

#+BEGIN_SRC python :results output

import pybout

f = pybout.Field("f")

g = pybout.Field("g")

f.ddt = g

g.ddt = -f

model = pybout.PhysicsModel(f, g)

print(str(model))  # Generates C++ code

#+END_SRC

#+RESULTS:

#+begin_example c++
