Abstract
The proposed work deals with the optimization of the distributed solver in EUROPLEXUS software (EPX, http://www-epx.cea.fr) when adaptive mesh refinement is used. It extends some previous recent work, dedicated on the one hand to the implementation of the scalable solver able to handle large topological changes in coupled systems with large displacements through a dynamic domain decomposition (for contact after impact or floating structures inside a fluid domain for instance), and on the other hand to the design of the versatile and efficient adaptive approach compatible with fluid-structure interaction with wave fronts, interfaces and structural failure. The compatibility of the adaptive framework with the distributed solver has been implemented, but it remains a significant step for parallel optimization, requesting a specific domain decomposition update strategy to design and program to retrieve the scalability levels achieved without adaptivity.
