ALE framework step-46

[ibryu...@gmail.com]

Hi,

I am looking for ways to solve a coupled problem in which a fluid flows through an elastic channel in a non-stationary formulation, i.e. a displacement of the walls is allowed. I found that step-46 allows to solve such a problem, but in the stationary formulation, where the channel walls are stationary and there are no time derivatives. The better models part describes ways to improve this step-46 using the Arbitrary Lagrangian Eulerian (ALE) framework. 

Could you suggest if anyone has any libraries under deal.II, or any ideas, articles, how a complete non-stationary problem could be implemented using deal.II, possibly by upgrading step-46?

Best regards,

Ilya
