3. DESCRIPTION OF PROGRAM OR FUNCTION

AXMIX provides a fast, simple,  and economical tool for creating cross-section data sets for ANISN and DOT from cross-section sets already available on cards, nuclide-organized libraries, and group-independent data sets. Numerous options including adjointing, Pn adjustments, changing table length, mixing, transport corrections of ANISN-type cross sections, and management of cross-section data sets and libraries are available.

4. METHOD OF SOLUTION

The number of energy groups which will fit into the core allocated is determined first. If all groups will fit, the  solution is straightforward; if not, then the maximum number of groups which will fit is processed repeatedly using direct access I/O routines written in Assembler language.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

AXMIX is limited in  its ability to process cross-sections with upscatter and extra caution must be used with them. This is due to the difference in the location of the total upscatter coefficient in ANISN and DOT cross-sections. A special section on upscatter is therefore included in the document.

6. TYPICAL RUNNING TIME

On an IBM PC/XT, 4.77 MHz, sample problem 1
took about eight minutes; sample problem 2 took only a few seconds.  The IBM PC/XT had an 8087 math co-processor.
