We study the performance of the mortar method incorporated with the dual Schur method for elastodynamic problems for structures modeled with incompatible finite element meshes.Although this method ensures kinematic continuity throughout the specified interfaces,such as material interfaces and interfaces between different mesh topologies,we are concerned with the performance of the method especially for the case that two mutually incompatible meshes have different sizes of finite elements and
