ENHANCE-04(2017WP) — MLF and RK3 time stepping
| Reported by: | gm | Owned by: | gm |

| Priority: | high | Milestone: | Unscheduled |
| Component: | OCE | Version: | trunk |
| Severity: | minor | Keywords: | MLF RK3 |

Description (last modified by gm)
Context
Introduce an optional RK3 time-stepping scheme. The scheme will:
- be a valuable alternative to the current Modified Leap-Frog (MLF, Leclair and Madec OM2009) scheme,
- prepare the futur introduction of a compensated time-space scheme,
- allow AGRIF to be exactly conservative, and
- make much more easier to use time coarsening of TRC and OFF-line variable volume calculation
Implementation
Chosen strategy : keep both MLF and RK3 time-stepping in the code. This means : first transform the LF scheme to be consistent with a 2-level time-stepping environment, and then introduce the RK3 scheme.

- Description modified (diff)
- Summary changed from ENHANCE-04(2017WP) — FBS and RK3 time stepping to ENHANCE-04(2017WP) — MLF and RK3 time stepping
- wp_comment set to strategy of implementation and design of the targeted code ~OK. Two big steps: (1) transform the leap-frog scheme (MLF) to be consistent with a 2-level time-stepping environment ; (2) introduce the RK3 scheme. Step 1 expected to be ready for the 2018 merge party whereas Step (2) is not assured at that time.

Step (1) (branches/2018/dev_r9838_ENHANCE04_MLF]) ready for the 2018 merge party while Step (2) is scheduled for WP2019.
