Default Mimic (copy) of a Boundary

Hello everyone,

In my simulation domain I have two different 'continua'-s - and there are some inlets and outlets on each continua.

I want to mimic (copy) the 'outlet' boundary conditions from one domain to the 'inlet' of other domain - obviously on the outlet I know the flow rate, temperature and the pressure. How can I replicate these parameters on the inlet of the other domain?

For example, on one of the outlets I have air at 1kg/h, 400C and 100mbar. I would like to have the same values as 'inlet' parameters somewhere else in the computational domain?

any help?

Many thanks,

Can you put a picture from your geometry?

Have a look at the attached picture - this is simplified version of what I have.

Basically, the parameters in 'Inlet-2' should be the same as 'Outlet-1' - that is the pressure, flow rate and temperature.

In other words, the gas should continue in the second pipe with the same conditions - the physics continua is not the same in both pipes.

If you select velocity inlet for the second inlet, then you can give the values to the temperature and flow rate.

Yes, that is correct but how can I apply the exact pressure? to have a continues pressure drop?

Try it with a table, auto extract and interpolate to a field function.
