1"""Run a tsunami inundation scenario for Busselton, WA, Australia.
2
3The scenario is defined by a triangular mesh created from project.polygon, the
4elevation data is compiled into a pts file through build_elevation.py and a
5simulated tsunami is generated through an sts file from build_boundary.py.
6
7Input: sts file (build_boundary.py for respective event)
8       pts file (build_elevation.py)
9       information from project file
10Outputs: sww file stored in project.output_run_time_dir
11The export_results_all.py and get_timeseries.py is reliant
12on the outputs of this script
