To prevent solution instability caused by sudden increases in the
timestep, such as when the maximum refinement level decreases, a new
parameter 'dt_jump_factor' has been introduced. This parameter controls
the allowable increase in the timestep.
By default, 'dt_jump_factor' is set to 1.05, permitting a maximum
increase of 5% from the previous timestep.
