1 | """Script for running a dam break simulation of UQ's dam break tank. |
---|
2 | |
---|
3 | The simulation is based on the simulation Matt has presented and will |
---|
4 | form part of the ANUGA validation paper. |
---|
5 | |
---|
6 | i want to compare the stage at .4m and the velocity at .45m. |
