Hi all,
I am using CHT to simulate the heat transfer between packs of cells,plastic gasket inserted between each cell,the surrounding air and the outer metal case that contains all the above stuff.
In the model，I have 4 inter-faces:case-air,cell-air, gasket-air,cell-gasket. Altogether 8 virtual boundaries are created and applied to the interfaces correspondingly and according to the boundary normal directions.
The problem I came up when calculating is:
Neighboring triangles are associated with different streams--this is not allowed.
Together popped up 4 sets of num_new_triangles corresponding to the 4 interfaces in the geometry surface.
How can I solve this problem? I'm not quite sure what the "triangle" here means.
Thanks for your help in advance!

P.S.
1.The case-air interface(yellow), the cell-air interface (dark blue) and the gasket-air interface( orange) can be seen in image 1.
2.Additionally, the cell-gasket interface(green) can be seen in image 2.
3.Image 3 shows the boundary settings.ImageUploadedByCFD Online Forum1475834400.687302.jpgImageUploadedByCFD Online Forum1475834415.419581.jpgImageUploadedByCFD Online Forum1475834425.887621.jpg

Hi,

It is hard to tell without examining your case setup. So is it convenient for you to send the question as well as the case setup to us at support@convergecfd.com, please? Thank you
