摘要：
The diffusion equation with non-zero initial condition is solved using the Boundary Element Method in the frequency domain. Complex frequencies are used in order to avoid aliasing phenomena and to allow the computation of the steady state response. One numerical example is given to illustrate the effectiveness of the proposed approach to solve diffusion equations in two dimensions.
