sandisk New Member sunny Join Date: Jan 2011 Posts: 29 Rep Power: 15	Do we need to change the time step if we change the velocity of the fluid in the pipe. I am running simulations for slurry flow flow in pipes and I need to see pressure drops for different reynold number. So with a time step for a particular reynolds number, i get my desired results but for a different reynolds number should I change my time step ?
