The disk space required for your simulation depends mainly on the amount of results you request to be saved. During a simulation only two or three other files, in addition to the data files containing the results are created:
· The specification file (also known as the pfs file, Parameter File Standard) containing the simulation specifications. This file will be placed in your present working directory and have a file extension of m21. It will only take up approximately 2 Kbytes.
· The log file describing the model set-up, the statistics of the files used and created during the simulation and a message for each time step completed. The file extension of this file, which will also be placed in your present working directory, is log and it will only take up to 200 Kbytes on the disk.
· A file for the continuation of a simulation, the hot file. This file only takes up disk space equivalent to 9 times the space taken up by the bathymetry file. This mean that the hot file will not take up more space than 100 - 200 Kbytes.
