I am using Transport of dilute species

I have a downflow packed bed reactor with 2 layers, the upper layer is made of mineral ”A”, the lower layer is mineral ”B”.
When the concentration “c” has been passed through mineral “A” it will enter in mineral “B”.

How can I set in the Model Builder that the concentration of “c” at the Outflow of layer “A” is equal to the concentration of “c” at the Inflow of layer “B”?

I have Inflow1 which has a value of 10 mol/m3
The value of Outflow 1 is automatically calculated by Comsol
The value of Inflow2 is the same value of Outflow1 (How can I put Outflow1 as my Inflow value in Inflow2?)

Regards,

You can simply set the inlet value in domain 2 to the outlet value of domain 1 using an averaging function. So if you want you outlet concentration at boundary 1, then in your inlet values at the inlet in domain 2 boundary 1 would be aveop1(cA). Or, you can use a boundary identify pair which would be more precise..
