Precise Thermal Simulations

ThermNet simulates the temperature distribution of specified heat sources. Full integration with MagNet provides accurate results for coupled electromagnetic-thermal analysis needs.

Here are just some of ThermNet's many useful features:
  • Simulates the temperature distributions caused by specified heat sources in the presence of thermally conducting materials and convective/radiative boundary losses.
  • Two way coupling with MagNet for heating effects due to eddy current and hysteretic losses in the magnetic system
  • Specify the amount of power that is dissipated in each component in the form of density
  • Easy to use and intuitive interface helps expedite building and analyzing your model
  • Advanced geometric and material modeling including temperature dependent material properties
  • Parameterization capabilities allow for "What-If" analysis

Brushless DC Motor in Motion with Temperature Effects
This is an example of a Brushless DC (BDC) Motor with Interior Permanent Magnets (IPM). The goal of the analysis is to predict the steady-state temperature of the motor and verify if the rotor magnets will demagnetize at that temperature.
