Concept of physical application
Concept of physical application
A physical application allows the solving of a problem described by an equation, the operating hypothesis and the boundary conditions.
The concept of physical application regroups information that concerns:
- the solved equation and the solving mode of this equation (model, formulations, approximations, …)
 - the operating hypotheses: characteristics of the material media and the material behavior, characteristics of the sources, …
 - the boundary conditions: infinite box, conditions of symmetries and/or periodicity, other conditions imposed by the user, …
 
Categories of applications
The basic applications can be grouped into three categories:
- magnetic applications
 - thermal applications
 - electrical applications
 
To these, the strong coupling between magnetic or electric with thermal application are added:
- magneto-thermal application
 - electrothermal applications
 
General operation
The previously defined applications can be classified according to the field states:
- static applications treat static (or steady state) phenomena in devices where the field sources are time independent
 - transient applications treat variables or transient phenomena in devices where the field sources are time dependent
 - steady state AC applications for devices where the time variation of the field sources is sinusoidal
 
Circuit coupling / kinematic coupling
Flux permits the user to carry out studies with circuit coupling and kinematic coupling.
- Circuit coupling: The circuit coupling introduces the electrical equations directly into the magnetic field computation, enabling the analysis of electric conductors and the supply circuit. We refer to field – circuit coupling (or coupling with circuit equations).
 
- Kinematics coupling: The Flux kinematic module enables the study of a moving part in a device subject to mechanical forces (springs, friction, gravity, etc.) and magnetic forces (magnets, coils, ...).
