In ANUGA, a hydrodynamic model. I need to define a boundary line. But How to make a dictionary 'boundary' that stores the edges on the boundary?
There is an inbuilt boundary available for the predefined rectangular domain. But I have to define a boundary line for my real problem domain.
Your answer will help me to progress in my project, Please reply
Also if required refer the pages I mentioned below in the attached manual, hoping helpful to get extra clarity.
Page - 7 To get general idea
Page - 9 How boundary conditions are assigned?
Page - 41 onwards To know meshing
Thank you all
Hi Ramesh,
Use any GIS package (QGIS) to digitise the boundary as a polygon. This polygon can have many vertices (i.e., as many edges). Copy the vertices (X,Y location coordinates in UTM projection) to excel and save as extent.csv. Now read this file in anuga as
bounding_polygon = anuga.read_polygon('extent.csv') # domain boundary
Do not forget to assign tags to as many edges that are defined in your extent.
See attachment for the sample file.
Hope this helps!
