◆ SplitScheme

strong

Time SPLITTING policy of the macro-step (hyperbolic transport H + source stage S).

Lie: H(dt); S(dt) once (Godunov, 1st order). THIS IS THE DEFAULT, bit-identical to history: a single solve_fields at the head of the step, advance then run_source_stage interleaved in the same block loop (cf. step()).
Strang: H(dt/2); S(dt); H(dt/2) (symmetric, 2nd order as soon as H and S are). Requires RE-SOLVING solve_fields BETWEEN the stages (cf. step()): see the comment of the Strang branch and docs/HOFFART_STEP_SEQUENCE.md (the SINGLE head solve_fields does not suffice for the 2nd half-advance, which would otherwise read a stale phi).
