**3. CODING LANGUAGE AND COMPUTER**

Fortran IV; IBM 360/370.

**4. NATURE OF PROBLEM SOLVED**

GOFRR (**G**raphical **O**utput of **F**luxes and **R**eaction **R**ates) was designed to calculate and plot
reaction rates of fluxes from the discrete ordinates particle transport codes CCC-89/DOT (2-D) and
PSR-117/ANISN (1-D). However, GOFRR can be used to plot any one- or two-dimensional array
plus 3-D perspective drawings, 2-D reaction rate and spectrum plots and can calculate axes scales and
perform symbol plotting.

**5. METHOD OF SOLUTION**

GOFRR produces a number of different plots from CCC-89/DOT or PSR-117/ANISN flux input.
A three-dimensional plot may be drawn in which the X and Y interval midpoint values and the reaction
rates are represented by the X, Y, and Z axes, respectively. A two-dimensional plot may be drawn
of the reaction rate with either the X interval or Y interval held constant. For a ``row'' plot, the X
intervals *vs* reaction rate is plotted for a single Y value. Similarly, for a column plot, the Y intervals
*vs* reaction rate is plotted for a single X value.

Two-dimensional plots may also be made of the neutron or gamma spectra from an X and Y value
in histogram form. A three-dimensional material or zone map may also be produced from an input
array.

**6. RESTRICTIONS OR LIMITATIONS**

GOFRR's array network is flexibly dimensioned for efficient use of storage space. This technique
requires that an estimate of the main storage needed for a problem be calculated, the estimate must be
specified as the common block size, and the estimate must be passed as a parameter to the control
subroutine.

**7. TYPICAL RUNNING TIME**

The running time for a GOFRR calculation depends largely on the number of intervals used in the
problem and also the number of 3-D plots requested. On the IBM 360/91 computer, most problems
will run in less than 30 sec CPU time.

**8. COMPUTER HARDWARE REQUIREMENTS**

GOFRR is operable on the IBM 360/370 computers. 270 K bytes of main memory are required for a block size of 18,000 words. The GOFRR load module has a default common block size of 1,000 words.

A CALCOMP plotter is required.

**9. COMPUTER SOFTWARE REQUIREMENTS**

A Fortran IV compiler is required.
