 The parallel mesh adaptation algorithm is based on iterative remeshing and repartitioning of the distributed mesh (see [1](https://hal.inria.fr/hal-02386837)). It is inspired by the [Yales2](https://www.coria-cfd.fr/index.php/YALES2) algorithm (see [2](https://onlinelibrary.wiley.com/doi/abs/10.1002/fld.4204)).
 ParMmg uses the [Mmg](http://mmgtools.org) software to perform the sequential remeshing steps.
