Demo: Hundhammerfjellet project 11 Demo: Hundhammerfjellet project In the present demo we look at the site of Hundhammerfjellet, located on the coast in the mid part of Norway. WindSim contains six modules. A complete project passes through all the modules as you are going to do in the present demo. Open WindSim and start a new project by choosing: File > New > Project. The New Project window is opened, Figure 3; set your project location by browsing your hard drive, push the button or use the default path, (C:\Documents and Settings\User_name\My Documents); leave the Layout name as Layout 1, and enter the name of you customer in the Customer field. If no GWS file is specified, then the grid.gws with the terrain from Hundhammerfjellet will be automatically copied from the WindSim installation area. Figure 3. New Project window. Elevation and Roughness data are read from the grid.gws file and imported in the new WindSim project. Click OK in order to create the project.
12 WindSim AS Terrain The first step in the micro-siting of a wind farm is the generation of a 3D model in the Terrain module. This involves choosing the horizontal extension of the area to simulate and the height above ground that you want to use in your simulations. This volume (computational domain) is then discretized into a system of hexahedral cells called grid or mesh. The computational domain is therefore built on a digital terrain in *.gws format containing information about elevation and roughness. WindSim can be run by using the default settings in properties, or the user defined settings can be specified. Notice that all bold settings in the Properties panel are the ones that have been specified by the user. In the Demo version of WindSim, the maximum number of cells in vertical direction has been set to 10 while the total maximum number of cells has been limited to 5000. In the commercial version of WindSim the maximum number of cells would typically be limited by the available computer resources. Models with several million cells could be simulated on a high performance PC. The very restrictive limitation of the size of the computational model means that you cannot trust the results of simulations run with the demo version of WindSim. Run the Terrain module by clicking on the Start button with the default settings (see below). You should now see the Figure 4 of Hundhammerfjellet in the Report frame (see figure below).
