we would like to announce the first public release of the

**multiphenics**library, based on FEniCS.**multiphenics**is a python library that aims at providing tools in FEniCS for an easy prototyping of multiphysics problems on conforming meshes. In particular, it facilitates the definition of subdomain/boundary restricted variables and enables the definition of the problem by means of a block structure.This version (v0.1.0) comes with several tutorials:

*

**tutorial 1**: block Poisson test case, to introduce the block notation used in the library.*

**tutorial 2**: Navier-Stokes problem using block matrices.*

**tutorial 3**: weak imposition of Dirichlet boundary conditions by Lagrange multipliers using block matrices and * discarding interior degrees of freedom.*

**tutorial 4**: computation of the inf-sup constant for a Stokes problem assembled using block matrices.*

**tutorial 5**: computation of the inf-sup constant for the problem presented in tutorial 3.*

**tutorial 6**: several examples on optimal control problems, with different state equations (elliptic, Stokes, Navier-Stokes), control (distributed or boundary) and observation (distributed or boundary).* additional tutorials on simple multiphysics problems are forthcoming in v0.2.0

I would be more interested in this if you described your contributions in a journal paper.

Thanks for the comment! I will keep that in mind.

It looks interesting and I am sure that your tool has its applications. But I miss a presentation of some killer feature that would convince me to rewrite my current code. Also, a good user manual would be very helpful for any new user.

Thanks, improvement to the documentation is definitely on our TODO list. Concerning your other comment, I would be grateful if you could contact me via email with more details on your current code!
