Completion statistics at time t = 1.6 seconds.
| Method | Starting Δt (s) | Number of iterations | Computation time (s) | Average time per iteration (s) |
|---|---|---|---|---|
| Explicit | 10−5 | 6605 | 21.588 | 3.2684 × 10−3 |
| Wave* | 10−5 | 510 | 2.7779 | 5.4469 × 10−3 |
| Wave | 10−4 | 522 | 2.8059 | 5.3753 × 10−3 |
| Wave | 5 × 10−4 | 411 | 2.1555 | 5.2445 × 10−3 |
| Implicit | 10−4 | 391 | 5.2934 | 1.3538 × 10−2 |
| Implicit | 5 × 10−4 | 387 | 5.2180 | 1.3483 × 10−2 |
Notes. Completion statistics for the numerical methods at t = 1.6 seconds with adaptive time-stepping, run on a 2D grid with [256 × 256] grid points. Starred methods have a higher hyper-diffusivity applied. All times are taken for a simulation run on 16 cores in parallel, and exclude processing of output data.
