initialize_runtime Subroutine

public subroutine initialize_runtime(ctx, cfg, nml_file, is_ok, message)

Populate ctx and bring the solver to a ready-to-run state.

Steps performed in order: copy config into context; initialise logger; allocate solver state from config; allocate work arrays; bind flux, recon, and time-integration scheme pointers; apply initial conditions; optionally load a restart checkpoint; log the effective configuration.
