Tuflow and estry manual Version 3

cell
Square shaped computational element in a 2D domain.
centroid	The centroid of a region or polygon.
channel	Flow/velocity computational point in a 1D model.
CnM	CnM is a Chezy C, Manning’s n or Manning’s M bed resistance value.
code	Code refers to the code assigned to cells to indicate a cell’s status. It must have a value of one of the following. -1 for a null cell 0 for a permanently dry cell 1 for a possibly wet cell 2 for an external boundary cell
command	Instruction in a control file.
control file	Text file containing a series of commands (instructions) that control how a simulation proceeds or a 1D or 2D domain is built.
DTM	Digital Terrain or Elevation Model
element	An element in a finite element mesh as written by TUFLOW for viewing the 2D grid and results in SMS.
fixed field	Lines of text in a text file that are formatted to strict rules regarding which columns values are entered in to. In previous versions of ESTRY and TUFLOW all text input was in fixed field format. These formats are still supported, and are still used in a few instances as documented in this manual. Refer to previous manuals for the full documentation on fixed field input. The following notation is used to define the type and width of the columns. “A” indicates a text (character string), “I” an integer, “F” a decimal or real number and “X” an unused single character space. For example, (A2, 3A1, 2I5, 5X, F10.0), indicates that input along the line starting at column 1 is a two character text (A2) followed by three single characters, then two integers over five columns each, five unused spaces and finally a decimal number over the next ten columns. The location of the text, integer or decimal number can occur anywhere within the columns designated.
fric	The field used to store bed friction information. This may be the material type or ripple height.
GIS	Geographic Information System that can import/export files in MIF/MID format.
