plshelp is on a distinguished road

I am trying to mesh my computational domain by applying the multizone method but I always get these errors:

- MultiZone blocking decomposition failed. If you right click on this message, you may be able to "Show problematic geometry" and try a different approach to meshing those bodies.
- A mesh could not be generated using the current meshing options and settings.

I don't know why it's doing this. it only happens after I apply boolean. can anyone pls help me understand why?

Are you manually selecting surfaces for splitting and sweeping? If not you may want to try that first and see if it helps.

As easy as it sounds, multizone mesh setup can be little bit tricky sometimes, especially with complex geometries and geometries with non-sweepable parts.

You may consider splitting your geometry in to several parts.
