The tesselated surface is not closed - One section is gone

Hi, this is my project link.

My problem is one of the sections gone missing after mesh operation.
Please advise.

Thank you.

Hi @pkvoon!

The problem is probably that your geometry is not watertight thus giving you an erroneous mesh. If you fix the watertightness there should not be such an error again but I have not figured out which part is affected. On top of that always make sure that the material point is inside your domain for internal flow analysis and outside your domain for external flow analysis.
