There are four input data files to be read by subroutine init. The first file consists of control parameters and is named funwave2d.data for 2-D programs and funwave1d.data for 1-D programs. With the use of intrinsic function NAMELIST in the program, variable name and its corresponding data can be put together. The logical device number for this file is chosen as 1 and the form of the files is ASCII.
The other three input files are water depth data, initial wave field data, and time series of source function amplitude, respectively. Their names are represented by f1n, f2n and f3n which are specified in funwave2d.data or funwave1d.data. Binary format is used for these three files to increase I/O speed for 2-D prograams while ASCII format is used for 1-D programs. Since the record length of data for binary format in SGI computer is different from other machines, a control parameter imch is used in funwave2d.data or funwave1d.data to adjust for different computers. +
