connecting two faces by UDF

aozdogan · December 31, 2014, 14:16

Dear Friends,
I am doing heat transfer analyses for the borehole heat exhanger and my CFD model has fluid flowing through the U-pipe. I have a U-pipe but not geometrically connecting at the bottom (two pipe side by side).So, is there any way to connect these two pipe at the bottom to get continues flow through the pipe.
Thanks and happy new year!!

As per description I am assuming that outflow of one pipe is the inflow of another.If it is the case you don't need UDF
You can try periodic non conformal interface..You may need to use translational periodic.. Check it out if it helps...
