A new method for the computational analysis of .uid-structure inter-action of a Newtonian .uid with slender bodies is developed.It combinesideas of the .ctitious domain and the mortar element method,by impos-ing continuity of the velocity .eld along an interface by means of Lag-range multipliers.The key advantage of the method is that it circumventsthe need for complicated mesh movement strategies common in ArbitraryLagrangian-Eulerian (ALE)methods, usually used for this purpose.
