Travel-time Run Log File (fmm.log)
All E4D travel-time modes record execution information to the E4D log file, <fmm.log>. In addition to the date and time of execution, the log file records all information required to reproduce the simulation, including the names of all input files and corresponding summary statistics. The log file also produces summary information concerning the number of processors used for the simulation, and the computational load on each processor. The <fmm.log> file is overwritten with each new execution of E4D. If necessary, users should rename or move <fmm.log> prior to additional E4D computations.
