Merge branch 'hongzh/symplectic-integrator' [PR #1049]
* hongzh/symplectic-integrator:
This branch implements symplectic time integrators.
We should come up with a unifying framework that works for all multi- methods such as multirate methods (see PR #1043). The idea of this branch is to ask users to provide a two-way splitting of the separable Hamiltonian system.
TSGetRHSFunctionSplit2w(TS ts,Vec *r,TSRHSFunctionSplit2w *fun1,TSRHSFunctionSplit2w *fun2,void **ctx)
TSSetRHSFunctionSplit2w(TS ts,Vec r,TSRHSFunctionSplit2w fun1,TSRHSFunctionSplit2w fun2,void *ctx)
The split/partitioned functions typically have an output vector that has lower DOF. For example, RHSFunction() represents a mapping Rn → Rn , but RHSFunctionSplit2w() provides a mapping Rn → Rn/2 since the subvector is always half of the combined vector. This is also why I use nested vectors for simplicity.
Using IS is a more general way to support multi-way splitting. I am not sure if we should use IS instead of nested vectors for symplectic integrators. Perhaps we can keep both approaches.
