Three dimensional simulation of complex structures

ABSTRACT Simulation of complex structures such as electromagnetic waves, smoke etc. is the technique we use to describe the shape of abstract or concrete objects. In latter studies we use the shapes of these objects to simulate the process for different time intervals. Geometric modeling provides a description or model that is analytical, mathematical, and abstract rather than concrete. We prefer such methods because it is a convenient and economical substitute for the real object or process. It is easier and more practical to analyze a model than to test or measure or experiment with the real object. From the point of ideas above simulation process in computer environment requires deep mathematical knowledge and also powerful computers equipped with powerful graphic computation capabilities. In this thesis we studied electromagnetic wave propagation with the support of required equipment mentioned. Keywords: Geometric modeling, complex structures, simulation
