Unknown walls generated when import .msh file to fluent.
I have a problem and need a help.
I made geometry like the picture, generated mesh and tried to calculate with fluent.
but the flow was interrupted by some walls.
I didn't make walls. (picture attached)
but fluent made some walls when the .msh file was imported.
I want to delete the walls or make them like interior.
how can I solve this problem?
please save me...
Make sure you had created all the Named Selections in Ansys Meshing that you need to declare, and when you inport the mesh into FLUENT, look at the list of mesh parts and display them. If some of the interior faces of the ducts have a wall BC's, chage it as interior faces, but by default FLUENT must import them as interior faces as well
I made named selections all over the body parts.
And walls didn't be generated inside when I import the mesh into fluent. But the problem was not cleared. Flows still couldn't go out. Then I focused on connections. Geometry and mesh model was comprised with many parts and contact regions were generated automatically to connect between parts. Then I made contact regions manually and the problem was solved.
I can make contact regions easily because of the named selections. If I didn't make named selections clearly, I cannot try to make contact regions manually because the model has so many parts and faces.
I'm so grateful for your advice. Thank you.:)
you can also put all the body pieces in one part (if you are using Workbench it's quite simple) in order to avoid the connections and have a conformal mesh :)
