Smaller time step size is required
WebbA value of +9 indicates a step distance of 1 gu and dynamic step size reduction with CV = 1/9. A value of 109 indicates a step distance of 1/ (1 + abs (109-100)) = 0.1 gu and dynamic step size reduction with CV = 1/9. Having particles moving approximately 1 grid unit per time step (e.g. T.Qual of 0 or 3) is typically reasonable. Webb4 maj 2024 · You can look at the documentation here (Thanks to edwinksl for pointing it out). %Your Code tspan = [3, 4]; %MATLAB here uses the in built step size %Set Step size. Say you want a step size of 0.1 tspan = 3:0.1:4; %This will run over only those values of t that are defined by tspan. Share. Improve this answer.
