Origami New Member Hongbin Wang Join Date: Feb 2020 Posts: 20 Rep Power: 6	I am modelling wind in built-in urban areas. The domain is (-1500 -1200 -4.65946) (2000 1200 500) in meters. The distance between the inlet and the outlet is 3500m. I would like the first 1000 time steps the time increment is 2 and later the increment is 1. How do I achieve this in controlDict file? Many thanks.
