| | 2 | |
| | 3 | == Identified strengts == |
| | 4 | |
| | 5 | * Supercritical flow (e.g. over weirs) as well as sub critical flows handled seamlessly |
| | 6 | |
| | 7 | * Bores handles well due to discontinuities allowed in solution |
| | 8 | |
| | 9 | * Numerically stable |
| | 10 | |
| | 11 | |
| | 12 | == Identified weaknesses == |
| | 13 | |
| | 14 | * ANUGA is not as fast as some other models |
| | 15 | |
| | 16 | * More diagnostics needed, e.g. time series, vector plots, extrema (dynamically store max stage/velocity: ticket:192) |
| | 17 | |
| | 18 | * Easy way of extracting time series - GA to provide example to Tom of extracting depth/veloctiy at a time step |
| | 19 | |
| | 20 | * Information on how sww file has been built not documented well enough |
| | 21 | |
| | 22 | * Wave attenuation over long distances and coarse grids identified by Will Power |
| | 23 | |
| | 24 | |
| | 25 | == Emerging opportunities for future work == |
| | 26 | |
| | 27 | * Time varying bathymetry ticket:191 |
| | 28 | |
| | 29 | * Validation for wave setup on planar beach (UQ interested in looking at this) |
| | 30 | |
| | 31 | * Culverts: ticket:145 |
| | 32 | |
| | 33 | * changing the mesh resolution - specify period of wave etc to work out maximum triangle size (adaptive mesh generation, ocean model from Imperial College) - inter-run adaptive mesh resolution - a better mesh tool - could we view the where the small triangles are? Interact with a GIS tool? By Xmas, Ted will have a nice GUI front end for flood modelling. |
| | 34 | |
| | 35 | * dynamic roughness - Manning's function - is the coefficient a function of depth? |
| | 36 | |
| | 37 | * fluid density - picking up debris (mud flow) |
| | 38 | |
| | 39 | * frequency dispersion |
| | 40 | |
| | 41 | * kinematic viscosity |
| | 42 | |
| | 43 | * optimisation; often only a few triangles causing small time steps - can they be dealt with heuristically? |
| | 44 | |
| | 45 | * subversion - third party contributions, isolate core of ANUGA. |
| | 46 | |
| | 47 | * applying a hydrograph at an upstream point |
| | 48 | |
| | 49 | * landslide over time rather than instantaneous (implement as forcing term) |
| | 50 | |
| | 51 | * randomly generated bathymetry - does is cause instability? |
