Error with spark ignition model
Please help me understanding the following error, and help me how to fix it.

ERROR #002100075 has occurred in subroutine SOLVE_RKERNEL. |
| Message: |
| |
| The spark region defined by the transition radius is empty, but at |
| least 1 mesh vertex is required to be located inside the |
| transition region. Consider refining the mesh in the region of |
| spark ignition or increase the transition radius. |
| |
| Domain : Exhaust |
| Fluid : Methane Air Mixture |

| An error has occurred in cfx5solve: |
| |
| The ANSYS CFX solver exited with return code 1. No results file |
| has been created.

I had this message once I putted wrong coordinates outside the domain.

Joey, I rechecked the coordinates I specified for the kernel center in the domain. However, I can't find anything wrong with the location of spark.

Is there any other possible reasons you can find for this error?

Thank you.

How did you generate the mesh? ICEM?

I used CFX Mesh tool for meshing. Ansys ICEM is better for meshing?

I'm a fresh hand in CFX. Could you tell me how they differ?

Since I'm doing combustion modeling, use of right mesh is critical for an accurate model.

Can anyone please help me regarding the error I'm getting with BVM Spark Ignition model.

The error I'm getting is quoted in the first post. I welcome all the valuable suggestions. Thank you.
