For easier comparison, return both the first order and residual viscosity when evaluating the residual. Add the first order and residual viscosity to the state of the RungekuttaRV time steppers

% Calcualtes the largest timestep smaller than k_max that gives an integer % number of timesteps to time T. % k_max -- largest allowable timestep % T -- time to align with % % Returns: % k -- calculated timestep % N -- number to of timestep to reach T function [k, N] = alignedTimestep(k_max, T) N = ceil(T/k_max); k = T/N; end
