Hi Govind,<br>
<br>
as promised, we have added a junior job to get in touch with writing<br>
Python bindings for DUNE, namely writing example bindings for our<br>
FieldVector class in boost::python.<br>
<br>
We think boost::python Bindings will be easier to maintain over the<br>
years (after all, we are C++ programmers). The downside is that we have<br>
to port or rewrite the work done in the BEM++ project. In our opinion,<br>
it's worth, though, because the bindings can be slimmer. Notice,<br>
however, that this is not yet a final decision and you are highly<br>
welcome to make another proposal by yourself.<br>
<br>
Best,<br>
<br>
Martin<br>

There is one thing one should consider and it is worthwile<br>
investigating this as part of the junior-job.<br>
<br>
The boost::python code is a horrible mess, as it still uses C++03. And<br>
as far as I know it is basically unmaintained.<br>
<br>
There is a new "version" called pybind11. It uses C++11, which<br>
dramatically simplifies the code and it is header-only, which I also<br>
consider a big benefit.<br>
<br>
Ciao<br>
