Feel free to check out, improve, review and participate in the development of the following projects

spacetime-genpod-burgers

Implementation of our space-time-parameter generalized POD and space-time Galerkin for solving Burgers' equation for various diffusion parameters. [Code] [Related Poster]

dolfin-navier-scipy

A Python package that provides an interface between *scipy* and *FEniCS* in view of solving Navier-Stokes Equations. *FEniCS* is used to perform a Finite Element discretization of the equations. The assembled coefficients are exported as sparse matrices for use in *scipy*. Nonlinear and time-dependent parts are evaluated and assembled on demand. Visualization is done via the *FEniCS* interface to *paraview*.
[Code] [Documentation]

lqgbt-oseen

A Python module for application of LQG-balanced truncation for low-order controllers for the stabilization of Navier-Stokes. As an example we consider the stabilization of the cylinder wake at moderate Reynoldsnumbers via distributed control and observation.
