Abstract
It is presented, in this paper, an error analysis for adaptive finite element approximation of fluid-structure interaction problems. A monolithic fully Eulerian formulation with conforming mesh is employed. In this work bi-dimensional domains, incompressible neo-Hookean solids and incompressible Newtonian fluids are considered. The h-adaptive refinement is done via red-green-blue algorithm implementation. The error analysis is based on dual residual method and the a posteriori error estimate is derived from it. This estimate is employed as criteria for mesh refinement procedure. An illustrative numerical application is analyzed, and the final results are presented.
