Zusammenfassung:The boundary element method (BEM) is a numerical technique which is now emerging as a viable alternative to finite difference and finite element methods for solving a wide range of engineering problems. The main advantage of the BEM over domain-type methods is its unique ability to confine the dependence of the problem solution to the boundary values only
This reduces the data preparation effort and saves computer time since the system of equations to be solved is smaller than those resulting from domain techniques. However, the main drawback of the BEM occurs in problems such as those with body forces, time-dependent effects or non-linearities. In these cases, the domain integrals that appear in the integral equation are usually evaluated by using cell integration
Although this technique is effective and general, it affects the overall efficiency of the BEM and detracts from its elegance due to the additional internal discretization
