To revert to the previous state, right-click or[BackSpace] press the key.
-
To cancel the creation,[Esc] press the key.
-
Confirm with double click or enter.
-
Select the mesh size of the calculation area.

Table: Calculation Area Property Names and Settings
| Property Name | What to set |
|---|---|
| name | Enter a name of your choice. |
| valid | Enable/disable settings. The initial value is True. True: Enabled: False: Disabled |
| Consider inland waters as oceans | Sets whether inland waters are treated as ocean or land. It is related to whether or not river run-up is considered during storm surge analysis. The initial value is "False" (treated as land). "True": Sea treatment "False": Land treatment |
| Line Style | Specify the line style (line type/line width/line color) to be displayed on the map. The initial values are as follows: Linetype: Solid Line Width: 2px Linecolor: RGB (128,64,0) |
| Gridline style | Specify the grid line style (line type/line width/line color) of the data (terrain, roughness, porosity, transmittance) to be displayed on the map. The initial values are as follows: Linetype: Solid Lineweight: 2px Linecolor: 50% gray |
Import from NetCDF¶
-
When you select the menu, the Import from NetCDF dialog (shown below) appears.
-
Select a file name, specify a variable, mesh size, and[OK] choose the button.
-
For more information about the netCDF file format, please refer to the Technical Reference I/O function/Terrain, roughness, and fill import function/NetCDF format.
Delete all compute space¶
When you select the menu, a confirmation message appears. [Yes] Click the button to delete all calculation space data.
