Python support in EAMxx

EAMxx has some limited support for interfacing with external python code. In particular, we allow calling EAMxx C++ code from a python module, as well as calling python code from inside an EAMxx atmosphere process. The former is described in this page, while the latter is described in this page. The two cannot be used at the same time.

NOTE: This feature is currently under development, so details may change in the future.
