COMPAR
Description
COMPAR works on FORTRAN arrays with four indices: A = A(i,j,k,l) where, for each fixed k0,l0, only the 'plane' [A(i,j,k0,l0), i = 1, isub(max), j = 1, jsub(max)] is held in fast memory. Given two arrays A, B of this type COMPAR has the capability to 1) re-norm A and B ind different ways; 2) calculate the deviations epsilon defined as epsilon(i,j,k,l): =[A(i,j,k,l) - B(i,j,k,l)] / GEW(i,j,k,l) where GEW (i,j,k,l) may be chosen in three different ways; 3) calculate mean, standard deviation and maximum in the array epsilon (by several intermediate stages); 4) determine traverses in the array epsilon; 5) plot these traverses by a printer; 6) simplify plots of these traverses by the PLOTEASY-system by creating input data blocks for this system. The main application of COMPAR is given (so far) by the comparison of two- and three-dimensional multigroup neutron flux-fields. (orig.)

COMPAR bearbeitet FORTRAN Felder mit vier Indizes: A(i,j,k,l), wobei fuer festes (k0,10) jeweils nur das Teilfeld [A(i,j,k0l0), i = 1, isub(max), j = 1, jsub(max)] im Kernspeicher gehalten wird. Liegen zwei solche Felder A und B vor, so kann COMPAR: 1) A und B auf verschiedene Weisen umnormieren, 2) die Abweichungen: epsilon(i,j,k,l): =[A(i,j,k,l) - B(i,j,k,l)] / GEW(i,j,k,l) berechnen; dabei stehen fuer die Wahl von GEW drei Alternativen zur Verfuegung; 3) Maximum, Mittelwert und Streuung der Abweichungen (ueber verschiedene Zwischenstufen) berechnen; 4) Traversen durch das Feld epsilon bestimmen; 5) diese Traversen auf dem Schnelldrucker zeichnen und/oder Eingabebloecke fuer Plots mit dem PLOTEASY-System erstellen. Das Haupanwendungsgebiet von COMPAR ist der Vergleich von zwei- und dreidimensionalen Multigruppen-Neutronenflussfeldern, die den geforderten Aufbau haben. (orig.)
