　　Time domain boundary integral equation method(TD-BIEM)for 2-D scalar wave problems is considered.The boundary integral equation is discretized with a temporal and a spatial interpolation function in TD-Bimini scalar wave problems in 2-D,the coefficient matrices of the discretized boundary integral equation are initially sparse but they become dense with time step since the influence from the source element propagates with the certain wave velocity.This problems are large scale problems because of these dense matrices.
