Induction heating
Billets, tubes and strips; power, coil efficiency and heating curves, steady and transient.
Induction heating and eddy-current NDT, predicted.
Coil over billet, strip or tube; probe impedance against lift-off and conductivity; shield effectiveness. Closed forms where they exist, FEM where they do not.
What does the Induction Heating & Eddy-current NDT do?
This module covers two industries that share the same physics. For induction heating it models a coil around a billet, tube or strip and predicts power, efficiency and the temperature over time, steady or transient. For eddy-current non-destructive testing it computes probe impedance over layered plates and rods versus lift-off, conductivity and permeability, the curves inspectors calibrate against. It also reports the shielding effectiveness of conductive and magnetic sheets. Classical closed-form solutions (Dodd-Deeds type) are used where they apply, with a FEM path for other geometries.
Features
Eddy-current probe impedance
Impedance-plane curves versus lift-off, conductivity, permeability and layer thickness.
Shielding effectiveness
How much a conductive or magnetic sheet attenuates a low-frequency field.
Material catalogue
Conductivity and permeability for common metals, with temperature dependence for heating.
Limits
Axisymmetric coil and workpiece geometries; complex 3D parts need the 3D Fields module. Temperature-dependent properties use catalogue data.
Every module ships with reference cases that run in our CI. See validation for how results are checked.

Frequently asked questions
Can it predict induction heating time?
Yes. The transient mode computes the temperature of the workpiece over time for a given coil current and frequency.
Does it model eddy-current probe lift-off?
Yes. It computes probe impedance versus lift-off and draws the impedance-plane curves used to calibrate eddy-current instruments.
