### Obstacle too thin in fluid-structure interaction, so I consider it as membrane

I need to simulate a 3D fluid-structure problem where the obstacle is an elastic and very thin structure (then I want to consider this structure as a surface). I need to solve this problem using ...

### Which algorithms(paper) should be reproduced by a student to enter the field of computational fluid-structure interaction?

We'd better not to reinvent the wheel. But without some programming, one can hardly understand computational fluid-structure interaction. And I would like to know which papers or algorithms should a ...

### How do we implement the balance of stress on interface in ALE FSI method?

""we aim for a consistent variational-monolithic coupling scheme in which we need all equations defined in the same domain; therefore, $\mathrm{ALE}_{f x}$ was introduced. In variational ...

### Is the weak form on this book about a level set FSI problem wrong?

I'm trying to repeat a level set FSI problem on the book <Level Set Methods for Fluid-Structure Interaction>, on the page 89, the provided freefem code define a weak form of the discretized ...

### Mesh movement method causing force oscillations in benchmark 2D FSI problems

I'm relatively new to the FSI world, and I'm dealing with some benchmark FSI problems at first; such as the example of a flap in a channel. (googling fsi benchmark flap 2D leads me to the example ...

### In level set fluid structure interaction method why can we rewrite the elastic force in this form while there is no shear force?

when we consider a Immersed Membrane Without Shear, we can define a regularized elastic energy as \mathcal{E}(\varphi)=\int_{\Omega} E(|\nabla \varphi|) \frac{1}{\varepsilon} \zeta\left(\frac{\...
