Force coefficients problem!
 
Hi, all, I have a puzzling question that the force coefficients depend on the time step strongly in my trancient simulation using Fluent, that is, the smaller time step, the larger force coefficeints. I cannot get why. Is my simulation scheme wrong? Can anybody give me any sugestion? Many thanks!
