Cylindrical needle to plane electric field

Problem Type:
Axisymmetric problem of electrostatics.

Geometry:

cylindrical needle electrode
Distance from needle tip to plane surface - 5 mm.

Given:
Relative permittivity of air ε = 1;
Needle potential U = 10 kV
Plate potential 0 V

Problem:
Determine the electric field strength distribution as a function of needle diameter d.

Solution:
Parametric analysis is automated with LabelMover tool.

Results:
Electric potential distribution around the needle, d=2 mm.
