Finish time for very long simulations

eduhmaia · September 17, 2015, 13:35

Hi guys

I'm interested in studying silting in reservoirs, which takes months - often years - for most effects to be fully visible.

I know FLOW-3d works with seconds as time unit, and using tens of millions of seconds as finish time is not doable at all. So is there a way to circumvent this?

Hello. You can focus your study on a particular area for critical sediment discharges and repeat for other parameters. But the area and time are certainly limited by computational power. A 1D software might be more suitable.
