Unstady boundary condition
 

Hi, i'm really new on this, and i only know how to modeling steady state. Now i have to modeling a inlet condition that varies with the time (i have diferents flows [L3/T] for each time in a table). How can i do that? please i'm very lost with this

Hi Rodrigo,
Could you explain more about your problem?
Do you have any equation for your inlet flow?
If your answer is yes you can calculate the flow inlet each time in your code.
If you're using a software for simulation, It depends on your software.

is the inflow laminar? what about the inlet geometry?
