Hello, 

I am trying to simulate combustion proces for my thesis and I am recieving vertex error as shown in the picture. I found out that one Normal is facing other direction than other so it means it has mesh problem but I am not sure if this causes the error. I appriciate every help.

Hello, 

There are certain conditions for applying periodicity, please see this section: 3.4.4. Periodicity Boundary (ansys.com)

Can you make sure all these are satisfied in your case?

Hello,

I think I solved the vertex error but have another error about spark ignition. The spark is located inside the chamber where it should be but still throws a spark plug error. Could you please help me? In the picture, you can see where physically the spark plug is located. 

Thank you very much.
