Physical Models employed in GNU Archimedes

This chapter describes the physical models employed in GNU Archimedes. It is important to fully understand this chapter in order to fully exploit the possibility offered by this code. Obviously, everything here is a brief review of what you can find in papers and books on the Monte Carlo subject. So, if you don't understand some aspects of this chapter, don't esitate to read the papers reported in this chapter. We will, also, describe the simplified MEP (Maximum Entropy Principle) model, which is a simplified version of the MEP model. This model has been developped by A.M.Anile and V.Romano, two professors of the Department of Mathematics and Computer Sciences of the University of Catania. It is a very good model, which is able to give very accurate results, compared to the other hydrodynamical models.

In the present release of GNU Archimedes we use a simplified version because it is enough for our purpose, i.e. the coupling of MEP model and Monte Carlo method in order to obtain very accurate simulation results in very short running times.

In the following we report a (i hope) complete list of usefull papers for people interested in the complete MEP model:
