Hello, I want to understand the detailed theory of the neo-hooken model for nonlinear solution in dealii-adapter. Are there any published literature references or documents related to this ?

Hi @cj1823149636
yes, we collected all related information in our dealii-adapter documentation [Theoretic details of coupled deal.II codes | preCICE - The Coupling Library](https://precice.org/adapter-dealii-solver-details.html)
If anything is still unclear, feel free to ask such that we can improve the documentation in this regard.
Best regards
David
