Computational solution of the atomic mixing equations: Special methods and algorithm of IMPETUS II. (English) Zbl 0909.65113

This paper is a continuation of part I [ibid. 11, No. 4, 189-205 (1998; reviewed above)], where a Fortran code to simulate atomic mixing and particle emission when a material is bombarded with energetic particles, has been given. The purpose of this paper is to describe the computational methods employed in the code to arrive at a resonably accurate and physically acceptable solution of the atomic mixing model. The underlying model consists of a system of partial differential equations that are solved by a finite difference method.
