The BOUSS-2D parameter file contains a series of comments and keywords that define the components and control the options of a simulation. Any line that begins withs "#" symbol is a comment and is ignored by the model. However, some utilities exist that may utilize comments.
Keywords begin with a ":" and are followed by values associated with the keyword.
The parameter file format is shown in Figure 1.
