Thank you for your answer, @kkanade. For my specific case, "Share" option did not work but "Merge" did, maybe simply because it was a combination of a volume/body and a plane/shell/surface/face element.
To all the users, this was the method I followed for my specific case:
1. Generate the 3D tunnel as a body element
2. Generate the 2D/zero-thickness obstacle inside the tunnel
3. Click on the parent element in the structure tree - change "Share topology" option to "merge" in the properties menu (See the video example in the previous post)
4. Save project
5. Open Ansys Meshing on Workbench
6. Create inflation on 2D surface
7. Generate mesh
- Get ready for the warning "Pre-inflation layer generation has stopped because of side face limitation, proximity collisions and quality." Even though I entered 5 maximum layers for inflation, there seemed to be only 1 on both sides of the obstacle as shown below
Here, if you pick the option "post" instead of "pre", you get the number of layers you want but the quality is still low and you still get the warning "Post inflation with layer compression has generated non continuous inflation layers. Please review the geometry and/or the meshing parameters."
I must say as an experienced Icem CFD user, quite a learning curve is required to migrate to the combination of Spaceclaim and Ansys Meshing because if you want to create high-quality inflation layers / boundary layer mesh on this 2D element for example, I think you have to follow a method more detailed than I mentioned above.
