Complex Variable Bondary Element Method (CV-BEM)

The boundary element method (BEM) is connected with elements of the boundary of a region. Boundary integral equations (BIE) serve as its basis. The essence of the method lies in a specific approach to solving such equations. The BEM uses additivity of integrals: an integral over a whole boundary (a surface in 3D or a contour in 2D) is equal to the sum of integrals over elements of which the boundary is composed or into which it is divided. So, first of all, the boundary is represented by a set of such elements termed boundary elements. This procedure is called discretization of a boundary.
