Physical Application
Magnetic Applications (General) A new model for magnet is put forward non linear magnet spline with transversal mu
Magnetic Applications (in FLUX3D) Inductors are suppressed and replaced by the electric component Coil Conductor A new mode for the description of composed coils is proposed Coils of dipole type are suppressed and replaced by a new type of source of magnetic field Magnetic field created by a magnetic dipole
Electric Applications A new type of region is proposed for perfect conductors modeling (in Electro Static and Steady state AC Electric) Perfect conductor
Thermal Applications The physical description could be done with a user temperature unit

Boundary Conditions

• Boundaries conditions are handled by the
  intermediate of
• Periodicity
• Symmetry
• Regions
• line regions (or point) in 2D
• face regions (or line) in 3D
• In FLUX3D, surface constraints are suppressed.
