Model diffusion through contact interface

Please login with a confirmed email address before reporting spam

Dear all,

I want to simulate the mass diffusion inbetween two contact parts. First I assemble two parts with a contact pair. Then in the 'Transport of Diluted Species' module, how could I set the contact interface as a diffusion continuity interface instead of 'no flux'? There is an option in the 'Pair' -> 'Continuity'. However, once I select the contact pair, this pair automaticallt becomes the "No Flux" as a subnode.

Best, Rong

Not quite sure what is the reason as I havent used assembly to solve transport process. But I do believe when you right click on pair you will see fallback features allowing you to use continuous boundary condition.

Thank you for your reply, Yu.

Actually, there is a subnode named 'Continuity' in the 'pair'. But as I metioned, even I assign the contact interface as 'Continuity', the subnode under 'Continuity' is still 'no flux' which means this interface is still ynder discontinuous boundary condition. So confused...
