hi.
i want to use inflation method, to mesh a body something like i had attached below.
when i apply the setting and click "generate mesh" the meshing method just apply for surrounding wall or lvg boundary , not both.
i want to use this method for both lvg and wall but although i select lvg boundary and surrounding wall but it does not work.
what should i do?!!!!!!
in the first picture surrounding wall is inflated and in the second picture the lvg surrounding ( cutted body in center) is not.

how do you know it is not meshed? the inflation layer cannot be seen becauase it is along the ZX axis approx. you can do a cut section from the middle of your geometry to see the inflation layer at the walls.

Hello Saeed,
While attachment, did you apply Boolean operation (unite/subtract)? If united then BL meshing will be created at the inner wall of the small body. If subtracted, then it will be created at the outer wall of the small body. In doing so, you have to cut the whole body so that surfaces of the small body are visible. While creating BL meshing select the surfaces of small body along with the main wall.
I think it be helpful.
