M'C

Overview

Magnetic field, vector potential, AC losses, loadline, inductance and magnetic energy, forces and resultants calculation in superconducting coil systems of arbitrary 3-D shape

Details

  • Analytical calculation of magnetic field and vector potential produced by isoparametric, 8-nodes brick elements. The brick elements are generated by automatic subdivision of higher level primitives (segments, coils, arcs) entered via a friendly command preprocessor

  • Revised AC loss calculation algorithm taking into account field penetration in superconducting filaments and cable shieldingcaused by coupling currents.

  • Maps of magnetic field, vector potential and AC losses on the conductors, along their length, for arbitrary scenarii of current ramps.

  • Magnetic field and vector potential can be computed and plotted in arbitrary sets of points along lines, plane grids or cubes

  • A number of plot options available, allowing for example to display coil system and results in the same 3-D view.

  • Calculation of the loadline of the magnet on its operating plane (i.e. maximum magnetic field vs. operating current)

  • Inductance matrix calculation for the system of coils up to a user's specified accuracy

  • Coil and system energy calculation.

  • Force maps inside the winding pack, as well as total force resultants on coils.

  • Linear coil systems (no iron). Field and potential calculations are analytical, that is exact up to machine accuracy.

Examples

Some examples of application of M'c, showing modelling capability and accuracy achievable with the code, such as:

  • the calculation of the magnetic field generated by a thick solenoid,

  • inductance of a toroidal magnet for Superconducting Magnetic Energy Storage (SMES) and

  • AC losses calculation in the superconducting poloidal field system of a fusion tokamak.
