The most important thing we build is trust

 

Multi-physics simulation coupling thermal, electromagnetic and circuit domains is used to determine the temperature rise, the changing properties of the coil as it becomes resistive and the magnetic field.

Simulation of a superconducting quench models the physical process of a superconducting coil becoming resistive. Typically, unless protection circuits are employed, when small volume of the superconducting magnet becomes resistive, the quench process will propagate the normal conducting region throughout the magnet.

 

Multi-physics simulation coupling thermal, electromagnetic and circuit domains is used to determine the temperature rise, the changing properties of the coil as it becomes resistive and the magnetic field. Coil and protection circuit currents and voltages are also calculated.

 

Non-linear behaviour of materials is included either using functional properties or functional tables. Critical current density as a function of flux density and temperature is also modelled via tables or functions.  Rate dependent losses may also be added to the heat input.

 

Features include:                      

  1. Non-linear materials including functional properties using tables
  2. Display of temperature, losses and currents during the quench
  3. Inclusion of protection circuits with non-linear components
  4. External coupling to Elektra dynamic simulation to include eddy currents in the support structure
