3.
DESCRIPTION OF PROGRAM OR FUNCTION - ANISN/PC solves the one- dimensional Boltzmann equation for neutrons or gamma rays in slab sphere, or cylinder geometry. The source may be fixed, fission, or a subcritical combination of the two. Criticality search may be performed on any one of several parameters. Cross sections may be weighted using the energy dependent flux generated in solving the transport equation.
4.
METHOD OF SOLUTION - The solution technique is an advanced discrete ordinates method which represents a generalization of the method originated by G.C. Wick and greatly developed and extended to curvo- linear geometry by B. G. Carlson at Los Alamos Scientific Laboratory.
5.
RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM - Problem size is limited by machine size. The energy group limit is 25 for the PC version.
6.
TYPICAL RUNNING TIME - Run times range from a few minutes to several hours hours, depending on the problem. In general, a 1.5 to 2 orders of magnitude increase in run time is seen between ANISN/PC on an IBM PC XT and ANISN-W on a CDC CYBER 176.
7.
UNUSUAL FEATURES OF THE PROGRAM - 8.
RELATED AND AUXILIARY PROGRAMS - ANISN/PC follows a series of developmental efforts over a period of years (see CCC-0254). It is a modification of ANISN-W (CCC-0255), the Westinghouse version which was based on the Oak Ridge National Laboratory work.

MACHINE REQUIREMENTS - The minimum hardware requirements for ANISN/PC are: an IBM PC or compatible, the 8087 math processor chip, a 10MB fixed disk, 640K Random Access Memory.
12.
PROGRAMMING LANGUAGE(S) USED - 13.
OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED - The Ryan McFarland IBM Professional FORTRAN compiler Version 1.0 was used to compile the programs under PC/DOS 3.1. The PLINK86-Plus Version 1.48 overlay linker was used to create an executable ANISN file of approximately 640K bytes. The PC/DOS Version 3.1 linker was used to link the APE32 and LMOD programs. The executable files are included in the package. The Lahey FORTRAN 77 compiler was used to create the executable files for the ANTOPC and ANTOAPE utility programs.

ANISN was designed to solve deep-penetration problems in which angle-dependent spectra are calculated in detail. The principal feature that makes it suitable for such problems is the use of a programming technique with optional data-storage configurations which allows execution of small, intermediate, and extremely large problems. It also includes a technique for handling general anisotropic scattering. For ANISN/PC the standard souce iteration method, accelerated by up to two single scale factors, is used for outer iterations. Inner iterations are accelerated either by a stabilized variable-mesh rebalancing scheme or by a linear diffusion synthetic scheme. A noniterative matrix inversion technique based on a reflection principle is used for diffusion theory inner iterations.
