A Generalized Approach to Transfer the Domain Integrals onto Boundary Ones for Potential Problems in BEM
Since 19781 the boundary element method has developed very rapidly, mainly because of several important advantages. One of these advantages is that the BEM requires only the discretization of the boundary rather than the domain. However, this feature is generally lost when the source or some non-linear terms are present in the governing differential equations. Domain integral terms exist in the formulation of BEM in these cases. A similar problem occurs in time dependent problems due to the need to compute the initial condition integrals over all the domain.
