Modeling of Low-Dimensional Semiconductors,but the system matrices in the Boundary Element Method are neither symmetric nor positive-definite; this can lead to difficulties in the solution of the eigenproblem or in transient analyses if the algorithms are not employed judiciously.

Textbook 2003 in many cases an alternative to the more widely used Finite Element Method. As with any numerical method, the engineer or scientist who applies it to a practical problem needs to be acquainted with, and understand, its basic principles to be able to apply it correctly and be aware of its limitation

Continuum Physicsstence of discrete, indivisible units (the elementary particles). According to this theory, all natural phenomena can be described -at least theoretically - by interactions between these particles. On the other hand, . assumes a continuous distribution of field quantities, thereby disregarding the d
