On the need of certification in computational electromagnetics based engineering services

During the last five decades computing power has become more widely available. Consequently the solving of practical engineering and scientific problems has shifted towards virtual computer based assessments. A new field based on mathematical models and modern computers arose from this development and is called scientific computing. This field consists of numerical mathematics, computer science and the relating engineering discipline. This field differs from laboratory experiments and theoretical work which are the common forms of engineering work. Nowadays computational electromagnetics is a self-contained engineering service. This paper approaches the problem of providing proof of reliability and creating confidence in this special industrial sector.
