- Fix bug when constructing closure for narrow stencils
- Update the residual outside of the RK time steps. At least for the inner convergence rate, updating the residual inside does not seem to be required.

% 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
