Debug ResidualViscosity
- Pass exact time derivative to RungeKuttaExteriorRV and use that for evaluating the residual
- Start bootstrapping from later time level with higher order bdf

% 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
