No worries @mculik5!
- Usually the information that the geometry is watertight can be found in the geometry event log but does not always have to be there
This is also important when using the snappyHexMesh operation because otherwise, it might simply mesh both “sides” of the model - inside and outside. To define what “side” we want to mesh we define the so called Material Point which decides if we want to have an external flow simulation or internal one.
- A tutorial for the splitting process can be found here: STL Split Geometry. This would also be helpful in this case to click on a surface and hide it to see if there are any defects that are hidden which might cause some glitches in the mesh. The splitting process does also leverage our potential to create boundary layer cells more easily. We had some cases in the past where just one solid was causing trouble generating the inflated boundary layer.
Was everything clear so far? Let me know if I missed something!
