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.
Each solver module is tailored to different design problems and is available separately for both 2D & 3D designs.
Static or steady-state thermal simulation
Transient or time-varying thermal simulations
- 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
