Abstract
An efficient technique is proposed for calculation of coupled modes of fluid-structure interaction systems. The algorithm is presented with symmetric matrix operation mentality such that one feels that a symmetric eigen-problem is being solved. Furthermore, it is proved that each left eigen-vector is related to the corresponding right eigen-vector through a simple relation. Therefore, subsequent transient analysis can readily be performed. Overall, it is felt that the method is very efficient and it is ideal to be employed in general purpose finite element programs for solving above-mentioned eigen-problems.
