Time Step Size
Hi,
I am running a flow past cylinder at Re=10000. I'd like to know how can I determine the eppropriate time step size to get the right drag, lift and vortex shedding. I notice when I cahnge my time step size from 1e-5 to 1e-4 my drag coefficient will change. Thanks. |
Re: Time Step Size
0.01 * Shedding period calculated from the Strouhal number is a good initial guess.
