A review of local non reflecting boundary conditions

Truncating the infinite domain with an artificial boundary and then analysing the problem in its finite domain is the most common way of analysing a wave propagation problem in an unconfined domain. Simulating non reflective conditions at the artificial boundaries are thus crucial to the accuracy of the numerical solution be achieved with a finite element analysis. Different types of wave transmitting boundaries are used in practice, which consist of infinite elements or spring/dashpot combinations. This paper presents a comprehensive review of wave transmitting boundaries found in the literature. Performance of these wav e transmitting boundaries are investigated by simulating them using the finite element software ABAQUS/Implici
