I'm confused about the offset options of shell definition. What determines that we use midplane, bottom or top?
Is the mesh orientation the same as the offset?
For example, I select midplane, but the mesh orientation is either bottom or top. Which one should I use? What conditions decide the bottom or top?
Thanks.
Hi Dongwei
use the preview to see which offset you should use. the shell is a zero thickens FEA model and you are working on solids right?
If you are confused by the name shell just imagine it is a "sheet of metal"
