indication	item	function
	guidance	Displays the playback state and simulation time.
	guidance	Δt, simulation calculation time, and mesh size.
	Playback position	Indicates the playback position of the simulation results. You can change the playback position by dragging the mouse.
	head	Moves the current playback position to the top.
	playback	Replays the simulation results from the current playback position.
	Playback speed	When pressed, a pull-down menu for the magnification selection of the playback speed is displayed. You can specify from 8x, 4x, 2x, 1x, 1/2x, 1/4x, and 1/8x.
	end	Moves the current playback position to the end.
	suspension	Stops playback and returns the current playback position to the beginning.
	1 step back	Pauses playback and displays the simulation results one step earlier.
	pause	Pause playback.
	One step forward	Pauses playback and displays the simulation results one step later.
	close	Exit the display of simulation results.

Maximum immersion depth display¶

Select the menu to display the maximum immersion depth on the map.

Output the maximum immersion depth display as text¶

When you select a menu,[Save As] a dialog appears.

Set the desired destination and output file name, and[preservation] click the button.

Figure: Text output of maximum immersion depth display (Save As dialog)
The calculation result file is stored in a text file where each item is separated by a comma and the line ends with CR+LF.
For more information about this file format, please refer to Technical Reference I/O functions/Export calculation results/Text format.

Maximum immersion depth display output by ASC¶

When you select a menu,[Save As] a dialog (shown below) appears.

Figure: Maximum submersion depth display with ASC output (Save As dialog)
Set the desired destination and output file name, and[preservation] click the button.

Maximum submersion depth display output in KML¶

When you select the menu,[Give it a name] the Save dialog (shown below) is displayed.

Select an output option.

Figure: Maximum submersion depth display output to KML ([Save As] dialog)

Table: Maximum Depth Output Options Items and Functions

| Output option items | function |
|-------------|---------|
| for 2D display | Output without specifying altitudeMode. <br>It sticks to the ground surface and appears. |
| for 3D viewing | Specify "relativeToGround" for altitudeMode and output. <br>It is displayed at the specific height from the ground surface defined by Google Earth. |

Set the desired destination and output file name and [preservation] click the button.

Output calculation results as a video¶

When you select the menu, the video output dialog (shown below) is displayed.

Figure: Video output dialog

Set output and input.

Table: Items and functions of output and input settings of calculation results

Output setting items	function
Output Folder	* The non-editable output destination folder is displayed. The folder you selected when setting the output file name will be displayed automatically.
Output File Name	[...] Press the button to [Save As] display the dialog. Set any destination and output file name [preservation] Click the button to update the settings.
Video Formats	Select the output format for your video. It supports WMV and MPEG-4.
Video length	Set the length of the video to be output.
Video size	Set the screen resolution of the video. The higher the resolution, the longer it takes to generate the video.
Video bitrate	Set the video bitrate. Normally, the default setting "Variable bitrate (high quality)" is fine. If you set an extremely low value for the screen resolution set for the video size, the image quality will deteriorate.

Input setting items	function
Frames per second	Set the number of frames (frame rate) to draw per second of video. The more frames per second, the longer it takes to generate a video.
Base date and time	* Displays the non-editable simulation start date and time.
Source length	* Displays the length of simulation time that cannot be edited.

Set the desired destination and output file name, and[preservation] click the button.

The progress dialog (shown below) appears. If you want to cancel the video output,[cancel] click the button.

File Name	Enter a file name.
Mesh Size	Select a mesh size. By default, the calculated mesh size is selected.
The origin of time	Select the origin time of the output file. Breaking: Starting from the start time of the breaking. Flooding: Starts at the time of water entering the 2D flood model.
comment	Valid only when NetCDF format is selected. Sets the string to be included in the comment attribute in NetCDF. Blanks are usually fine.
Compression level	Valid only when NetCDF format is selected. Set the NetCDF compression ratio to 0 (no compression), 1 (low compression) ~ 9 (high compression).
Symbol mark number	Set the symbol mark number from 1~4. This number is used in other formats such as DXF.

※WL_STATION. Store the CSV in the folder specified in the "Guidelines for Digitization of Flood Expected Area Map Data (3rd Edition)" (Reference 34), and WL_STATION the "file name" set in the export dialog of the calculation result. When the calculation result is exported with the CSV breaking point No. matching, the breakage time is WL_STATION. Add to CSV.
