control_relaxation_materi_velocity index group_materi_velocity_relaxation

Relaxation parameters for velocity. This parameter only enters the left hand side of the iterative scheme. If enough iterations are used (see control_timestep_iterations), the parameters do not influence the final results.

You typically need relaxation in quasi static calculations where you don't have inertia group_materi_density. Then time stepping is only a process to go incrementally to the final solution.
