Abstract:

The FEARS program normally takes the problems descriptive data from the run-stream. This input data is composed of the Geometry and of the BilinearError matrices. Alternatively, this data can be read from a DUMP-file, which has been generated by a previous execution of FEARS. Once the initial data is read, FEARS enters into a command-mode. In the command-mode, the user must input a command with some parameters instructing the program about the next step to be taken. This mode allows the user to have complete control over the iteration process, step by step, reflecting the research nature of the program. On the other hand, the ITERATE command allows the iterations to be automatic. Once a STOP command is given, the run will be terminated. Printed output generated by FEARS consists of summary data after each iteration step. The user also has the option to reprint initial input andor detailed information about the solution process during the iteration. The formats of these printouts are described. In addition, the DUMP command generates a dump-file of the data structure which can be used as input, either for FEARS itself, or for various postprocessors. Chapter 5 gives the computer dependent control statements necessary to run FEARS on the UNIVAC 1100 computer. The program is supplied with a dummy subroutine giving zero values for the bilinear matrices E and D. If these matrices are coordinate dependent, the user must supply the appropriate subroutine replacing the supplied dummy routine. This preparation must be performed prior to the use of FEARS.
