Graphical interface for generating mesh for AnuGA model
This is a simple plugin to generate mesh for AnuGA:
https://github.com/GeoscienceAustralia/anuga_core
You need to have AnuGA and QGIS installed on your computer.
Download this repo as zip file, extract the zip file and place the folder under QGIS plugin directory (in Windows for example: C:\Users\NAME.qgis2\python\plugins\ in Linux: ~/.qgis2/plugins/python
First you need to define your GIS input layers:
Define a polygon layer for defining areas of different resolution with attributes Type (char) MaxTriArea (float)
- Type (char):
- B - boundary polygon
- H - hole (needn't have a maxtriarea)
- I - internal region
- MaxTriArea (decimal)
- Maximum triangle area
Define a line layer, with the following attributes, ensure the layer is snapped to the boundary polygon entity above. You can use AutoTrace plugin.
- Type (char):
- BT - boundary tag
- Name (char)
- its name
For further information about file formats, see qgis_anuga_gui_plugin_test_data.zip under test\data
Run the plugin and select relevant layers to generate mesh.
