URF vs Time Step Size
Hi,
What is better to achieve the convergence? Lowering URF or reducing Time step size? Thanks |

But don't you think reducing time step has a bigger effect on solution than URF? and what is the lowest value of URF you can use? Regards |

Theoretically speaking the lowest URF would be something very small but > 0. |
Thank you for your reply

Isn't URF somehow related to the Courant number as well. If that is the case then URF will effect courant number, likewise, time-step also effects courant number. Hence, stability of the problem would depend on URF and time-step size!!
