An arbitrary number of header lines can be added at the top of the file. Particular keywords terminated with a colon in column 20 are interpreted by WindSim. Some of the keywords are followed by mandatory input, others are optional.
The format version number does not follow the WindSim version number. The format version number is equal to the current WindSim version at the time when the format was last upgraded. Hence, a given format version m.n can be used together with WindSim version m.n and all post WindSim m.n versions.
After the header information, follows the grid information, presented in a regular grid, starting at the bottom left-hand corner (south-west) proceeding towards east (nxp) and then towards north (nyp). Line numbers for each west-east line are given separately to enhance readability of the data. The different grid information is grouped after its respective keyword, i.e. Height: then Roughness:.
