3. DESCRIPTION OF PROGRAM OR FUNCTION
FED reduces the effort required to obtain the necessary geometric input for problems which are to be solved using the heat-transfer code, TRUMP (NESC 771). TRUMP calculates transient and steady-state temperature distributions in multidimensional systems. FED can properly zone any body of revolution in one, or three dimensions.

4. METHOD OF SOLUTION
The region of interest must first be divided into areas which may consist of a common material. The boundaries of these areas are the required FED input. Each area is subdivided into volume nodes, and the geometrical properties are calculated. Finally, FED connects the adjacent nodes to one another, using the proper surface area, interface distance, and, if specified, radiation form factor and interface conductance.

8. RELATED AND AUXILIARY PROGRAMS
FED provides TRUMP Block 4 and Block 5 input. Block 4 input consists of listing each node number, its associated material number, and three geometric factors whose product equals the node volume. Block 5 input is a list of the connected node numbers, the heat conduction paths from the nodal points in the connected nodes to the connected interface, two geometric factors whose product equals the connected interface area, the interface conductance, and the thermal radiation form factor.

14. OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS
The IBM version generates graphic output through calls to the proprietary CalComp subroutines AXIS, FACTOR, LINE, NUMBER, PLOT, PLOTS, SCALE, and SYMBOL. These subprograms are not included. Function ICLOCK, written in Assembler language, returns the elapsed CPU time. The CDC version generates graphic output through calls to the LLNL TV80LIB and ORDERLIB libraries subroutines CRTID, DUMP, EMPTI, EMPTY, FRAME, KEEP80, LINE, MAPS, MARKER, NUMBER, PLOT, PLOTE, PLOTSC, SETCH, SETLCH, and SYMBL4. These are not included; dummy routines are substituted. Suitable alternatives for the "missing" plot routines must be supplied if graphics output is desired.
