Spark plug electric field

Problem Type: electrostatics.

Geometry: 3D import.

Given:
Relative permittivity of air ε0 = 1,
Relative permittivity of insulator εr = 5,
High DC voltage V = 15 kV.

Task:
Calculate the electric field stress distribution in the spark plug air gap.

Solution:
We simulate only the area around the spark gap. The other parts of the spark plug are excluded.

Results:

Electric field distribution in the spark gap:
