Coupling GSM/ALE with ES-FEM-T3 for fluid–deformable structure interactions

摘要: Abstract In light of the effectiveness edge-based smoothed finite element method (ES-FEM-T3) and arbitrary Lagrangian–Eulerian gradient smoothing (GSM/ALE) in, respectively, solving pure solid fluid flow problems using three-node triangular elements, they are coupled together in present study to solve more challenging fluid–deformable structure interaction (FSI) based on weak coupling algorithm. Specifically, is tracked over moving mesh with well developed GSM/ALE transient response part solved by newly explicit ES-FEM-T3. The solutions from these two parts “linked” carefully formulated FSI conditions interface. Detailed procedures summarized illustrate implementations ES-FEM-T3 an analysis. Three benchmarks employed validate proposed both steady-state problems. sensitivity analysis further carried out showing that results system appear sensitive change as compared mesh, thus suggesting a refined for part. Another significant finding can still produce reliable even extremely distorted near successful serves good start implementing family methods complex cross-area
