---|
2 | |
---|
3 | Source data such as elevation and boundary data is assumed to be available in |
---|
4 | directories specified by project_urs.py |
---|
5 | The output sww file is stored in project_urs.output_run_time_dir |
---|
6 | |
---|
7 | The scenario is defined by a triangular mesh created from project_urs.polygon, |
---|
8 | the elevation data and a simulated tsunami generated with URS code. |
