SIMHEAT® is simulation software dedicated to the heat treatment process. SIMHEAT® is the effective solution to simulate metallic alloy (including carbon steel and aluminum) heat treatment processes and gain true workpiece distortion, residual stress, and microstructural evolution insights.

Induction heat treatment simulation provides comprehensive information about temperature gradient from surface to core and where phase transformations occur.

SIMHEAT® can monitor the impact of current frequency, coil geometry, and even concentrators’ location within the heat-affected zone. Material modeling considers electrical and magnetic properties that are temperature-dependent.



  • A multi-physics approach to capture ‘mechanical-electromagnetic-metallurgical’ phenomena
  • Monitor inductors and concentrators in motion to image rotating parts and induction equipment (e.g. case hardening of a crankshaft)
  • Up-to-date modeling of the generators that adjusts current intensity and frequency to maintain prescribed nominal power values
  • Prediction of heat affected zone and metallurgical transformations to identify austenitized areas prior to quenching
  • Local mesh adaptation based on the temperature penetration depth


Predict, qualify, and quantify defects of the final part with the most accurate, and fastest software available on the market. Mistakes are made on the computer only, not in production.


With SIMHEAT® you can:

  • Full compatibility with JMatPro® database
  • Generation of Kirkaldy-based TTT diagram for low-alloy steel grades
  • Import tailored CCT diagram in text format
  • Carburizing: offset of transformation kinetics as a function of carbon rate
  • Age hardening based on Shercliff-Ashby models for heat-treatable aluminum alloys
  • Distortion models applicable to any kind of metal including aeronautic alloys
  • Material sensor tracking to plot characteristics over processing
  • Exhaustive results: temperature, phase transformation, HV or HRC hardness, distortion, residual stress, yield stress, carbon and nitrogen concentration, etc.


  • Predictive Solution: simulate all your thermal cycles thanks to models for heating, quenching, annealing/tempering, carburizing, nitriding, and controlled cooling. SIMHEAT® predicts phase changes, hardness, residual stresses, and distortions in your parts.
  • TTT & CCT Diagram Generator: for low alloy steel grades based on their chemical composition and initial grain size.
  • Heat Transfer Coefficient Identification: With SIMHEAT® optimization module inverse engineering capability, you can easily identify the precise values ​​of your process parameters.


SIMHEAT® can be used as a standalone solution or in combination with Transvalor software. All the capabilities and functionalities of SIMHEAT® are also integrated into our FORGE® software, which is dedicated to the simulation of hot, semi-hot, and cold forming processes.The perfect interoperability guarantees seamless results transfer from one solution to another.
