Is a parallel implementation of 3d fluid-struction interaction algorithm (no matter what types of algorithm) in freefem, a paper or a piece of code?

We do have an unpublished [piece of code](http://jolivet.perso.enseeiht.fr/FreeFem-tutorial/2019.pdf#page=53) for strong coupling. For weak coupling, there are a couple of references available, see [[1](https://www.sciencedirect.com/science/article/pii/S002199912030348X), [2](https://www.sciencedirect.com/science/article/pii/S0307904X21003966)].
