QUENCH solves the physical process of a superconducting coil becoming resistive. Once initiated, the quench process will propagate, as the quenched volume becomes resistive and produces ohmic Joule heating.

To analyze this, a coupled thermal and circuit model is used to represent the temperature rise, and the changing properties of the coil as it becomes resistive.

The non-linear behaviour of materials is included either using functional properties, or using functional tables (which allow properties to be functions of up to 3 other quantities).

QUENCH features include:

• Full 3D modeling
• Automatic Mesh Generation of coils
• Efficient Data Input
• Non linear materials including functional properties using tables
• Interfaces to CAD/CAM
• Display of temperature and currents during the Quench
• Full 3D modeling
• Inclusion of protection circuits

Critical current surface, defined as a function of magnetic flux density ans temperature. The definition is stored as a functional table.
