Flood modelling in urban areas : A comparative study of MIKE 21 and MIKE FLOOD (English) If an element has fewer nodes than the maximum number of nodes per element stated in the element header line then the remaining node Id value is 0.įor additional information, see the DHI User Guide. Each line contains information for one element in the format as follows:Įach line contains at most as many nodes as stated in the element header line.

Element lines – Every line after the element header line for as many lines as stated in the element header line.

Internal code for mesh type (21 for purely triangular elements, 25 if quadrangular elements exists).

The maximum number of nodes per element.

Element header line – One line containing three numbers.

The node type (0 for water, 1 for land and above 1 for all other boundaries).

The y coordinate (Northing or Latitude).

The x coordinate (Easting or Longitude).Each line contains information for one node in the format as follows: Node lines – Every line after the header line for as many lines as stated in the header line.

This followed by the number of nodes then by a string defining the projection. This line contains two integers expressing the type and unit of the bathymetry data. In the Open file dialog change the Files of type to "Mike 21 files (*.mesh)"Ī MIKE 21 mesh file uses the following format:.

SMS reads the grid, stores it as a two-dimensional unstructured mesh and allows the user to associate it with any of the numerical engines supported in SMS by using the Data | Switch Current Model command.

If a grid/mesh is available in this format, it can be loaded into SMS and used for further model construction/management. The MIKE 21 program is produced and distributed by the DHI group. It lists the node and a simplified element table in text format using spaces as separators. The text file defines a simple unstructured grid and is similar to a *.2dm file. A MIKE 21 mesh file is a text/plain file and has the *.mesh extension.
