Solver settings for transient analysis of flow over a 2d cylinder

can anyone tell me what solver settings to use while performing transient analysis for flow over a 2d cylinder...
momentum and pressure..??
thanks

Defaults are good. Just figure out what time-step size you need (try to have a small Courant number). And then figure out how many iterations per time-step you need to get a converged solution every time-step. Figure out means actually go and do it! Press the run button with any settings and then learn from there. There will be some trial-and-error until you get the right settings.
