Predefined computations
Definition: reminder
Predefined computations are computations of global quantities dependent on the activated physic application.
It can be a question of:
- the magnetic force Fm, magnetic torque Γm, magnetic energy Wm, etc. in case of a magnetic application
- the electrostatic force Fe, electrostatic torque Γe, electrostatic energy We, etc. in case of a electric application
- the heat flux, etc. in case of a thermal application
Magnetic applications: principles
Use
The predefined calculations can be carried out in two ways:
- directly: by the command Predefined calculations in the Advanced menu
- indirectly: by using a sensor
Predefined computations
The predefined computations (energy, force, torque, etc.) are presented in the table below. They are dependent on activated physical application.
| Computations | Description | |
|---|---|---|
| Computation domain | … | |
| Magnetic force / Electrostatic force | volume / face / line region | |
| Magnetic torque / Electrostatic torque | volume / face / line region |
+ rotation axis (direction / pivot point) |
| Magnetic energy / Electrostatic energy |
volume region face region line region entire domain |
|
| Losses by Joule effect | ||
| Flux through a coil conductor | stranded coil conductor | |
Predefined computations and IB
To compute on the entire domain:
if there is an infinite box, then the computation takes it into account, the quantities are computed “to the infinity”.
Predefined computations and symmetries / periodicities
In the presence of symmetries/periodicities:
computations are performed for the part of the device represented in the computation domain, except the computation of Flux through a coil conductor, which takes into account the symmetries / periodicities (see § Multiplying coefficient for computation of flux through coils).
Storage
predefined calculation is stored as an entity in the tree of the general data in the entity type Result of calculation under the root of the Postprocessing repertory
