How to animate 1D flood map results

You can associate your 1D results with a triangulated water surface (TIN file) and use the 1D Flood Map tool to create a 2dm/dat format results file. This is the same format as created from 2D simulations and hence these data can be animated within the Flood Modeller map view (on top of any user specified background mapping).

The steps to produce this animation are as follows:

1. Load TIN file and underlying grid into Flood Modeller map view
2. Load a grid dataset that represents underlying ground elevations. This can be in ASCII raster format (.asc) or binary format (.flt).
3. Associate your 1D results data to the loaded TIN. Right-click on the TIN file in the Layers panel and select Load Results from the displayed menu. This prompts you to specify a 1D results file (either binary (.zzn) or comma separated (.csv) format). A new window is then displayed for you to select which time steps and which results parameter to associate to the TIN. See the Create a TIN section for guidance on this procedure.
4. Access the 1D Flood Map tool, located in the Results tab of the main toolbar. Specify your flood map calculations as follows:
   1. Select your TIN and underlying grid file from the displayed lists
   2. Select a set of time steps (use the Shift and Ctrl keys for multiple selections)
   3. Click the Add or Run button. The Add button creates a batch list of required processes allowing inspection before you start the calculation process. The Run button will set up the same list of processes but start them immediately. For both cases you must select the option to output data to the 2D results (2dm/dat file) format.
   4. After specifying your output files proceed with the calculations (click Save on the Browse window or Run on the 1D Flood Map window). The calculation process may take time as many flood maps must be calculated separately and combined in the output file. A message box displays progress through the calculation.
   5. The resulting output can be loaded into your map view, where you can animate the sequence of time steps and record these data to a movie file using the same procedure as for 2D model results data (see below).
