Shredding frequency vs Time step size -- CFD Online Discussion Forums

May 14, 2006, 05:48	Shredding frequency vs Time step size	#1
Leo Guest Posts: n/a	Hello, All! I hope you excuse my English. I modelling flow over a cylinder.For verification of results, I must find shredding frequency (Strouhal). But this value is different for different Time step sizes. (greater time step size gives smaller value of frequency). Is it normal?
