Structure damage analysis due to shock wave

[Hyung Seok Kang]

Dear All,

I am Hyung Seok Kang of Korea Atomic Energy Research Institute in South Korea.

I am now investigating that deallii can simulate a solid structure damage when a pressure wave, owing to a hydrogen explosion, collides with the structure.

I would like to analyze a FSI analysis using OpenFOAM, preCICE, and dealii.

Colud you please inform me a proper tutorial or case study?

My background is a CFD researcher, especially for hydrogen explosion.

So, I need your advise.

Best Regards,

Hyung

Hyung:
which tutorial program is most related to a specific application is often a
question of the "character of the equations" you want to solve, rather than
the physics behind them. For example, if you need to describe the pressure
wave as a first-order hyperbolic system because the wave is strong, then you
should take a look at the programs that solve the Euler equations of gas
dynamics (e.g., step 33, 67, 69). On the other hand, if the wave is weak, then
you can just use the regular second-order wave equation for which steps 23 and
25 are the closest. Similarly, you need to think how exactly you want to
describe structural damage.

In general, deal.II has been used for pretty much any application anyone can
think of as long as it can be described as a PDE:

How one would best approach using deal.II for your application very much
depends on the equations you want to solve (more than on the physics that
these equations describe).

Best
W.
