5.2. Iterative Methods

These tutorials examine how groupset solver choices affect the route to a converged transport solution. The inner-solver and GMRES comparisons hold the physical model fixed so differences in iteration behavior can be separated from changes in the underlying problem. The scattering study instead varies the scattering ratio to show how the problem itself controls the convergence of each inner method.

See the iterative-methods reference for all available methods and convergence controls.
