Problem Type
Axisymmetric multiphysics problem of DC magnetics coupled to Stress analysis.

Geometry
Inner radius R₁ = 1 cm, outer radius R₂ = 2 cm.

Given
Current density j = 4 MA/m²,
Coil Young modulus E = 107.5 GPa, Poisson ratio ν = 0.33.

Task
Calculate the mechanical stress distribution.

Solution
In this example, we ignore the end effects and model the central part of the solenoid only.

Result
