Internal sink source boundary condition - how to do?
1 Attachment(s)
Hello Fomers!
I got a problem with the BC, as the follwing graph, for some reason there is a surface sink source in a flowfield, this means the both spieces A and B disappear on the single middle surface. Like they rush into a blackhole. How can i set the bondary condition on that surface? I tried: 1. topoSet--> to choose the middle surface 2. blockMesh: leftside { type cyclic; faces ( ); neighbourPatch rightside; } ...--> to give the patch. 3. in Terminal: createBaffles middleSurface '(leftside rightside)' -overwrite --> to split the middle surface into 2 surfaces: "leftside" and "rightside". But i got the problem with the "cyclic" boundary condition, :eek: it seems like i can not use the "cyclic" BC for a sink source. But i really need to split that middle surface into 2, because i need 2 "outlet" for the both speices. What can i do with that kind of BC:confused: Attachment 19771 Thanks, Q. Cao |
