Coupled Analysis Subcycling

  • A much greater degree of freedom for coupled analysis timing in JMAG!
    • Choose either magnetic field or thermal analysis as time standard for coupled analysis
    • Choose multiple studies in slave analysis

Coupled Analysis Subcycling

Multi-frequency Heating

  • Account for multiple frequencies in coupled magnetic field thermal analysis!
    • Estimation of dual wave properties in high-frequency induction heating
    • Respective losses from different superimposed frequencies can be analyzed by specifying multiple magnetic field analysis (FQ) files

Electromagnetic Field Calculation at Any Coordinates

  • Purpose
    • Obtaining a high-resolution electromagnetic field distribution that is not influenced by the original air region mesh
  • Features
    • High-speed calculation is realized because recalculation from redivision of mesh for air regions is not necessary.
    • Rectangular/Cylindrical/Spherical coordinates available
    • Resolution determined by number of divisions for each axis
