Simcenter MAGNET Thermal
Simcenter MAGNET Thermal couples with MAGNET or MAGNET Electric for accurate temperature predictions.

MAGNET Thermal (was ThermNet) simulates the steady-state and transient temperature distribution of specified heat sources. Coupling with MAGNET and MAGNET Electric provides accurate electro-thermal analysis for devices such as electric machines (motors and generators), transformers, induction heating, surge arrestors and dielectric heating.
Overview
MAGNET Thermal accurately simulates the temperature distribution as a result of heat rise or cooling in your electromechanical device. MAGNET Thermal seamlessly couples to MAGNET's electromagnetic and MAGNET Electric's electric field simulations for further analysis: use power loss data from MAGNET and MAGNET Electric as a heat source and determine the impact of temperature changes on the overall design and performance.

  • Simulates the temperature distributions caused by specified heat sources in the presence of thermally conducting materials
  • Coupling with MAGNET for heating effects due to eddy current and hysteresis losses in the magnetic system
  • Coupling with MAGNET Electric for heating effects due to electric losses

Each solver module is tailored to different design problems and is available separately for both 2D & 3D designs.

Static or steady-state thermal simulation
  • Determines the non-linear steady-state temperature distributions caused by specified heat sources
  • Accounts for heat transfer due to conduction, convection and radiation
  • Both adiabatic and non-adiabatic thermal processes can be simulated.
  • Couples with all MAGNET electromagnetic field solvers
  • Couples with transient, current flow and time-harmonic electric field solvers in MAGNET Electric

Transient or time-varying thermal simulations
  • Determines the non-linear steady state temperature distribution caused by specified heat sources
  • Accounts for heat transfer due to conduction, convection and radiation
  • Both adiabatic and non-adiabatic thermal processes can be simulated.
  • Adaptive, fixed interval and user defined time stepping
  • Second-order time stepping
  • Resume Feature: pause at a particular time step for inspection
  • Couples with all MAGNET electromagnetic field solvers
  • Couples with transient, current flow and time-harmonic electric field solvers in MAGNET Electric
