Tmmfe_ht Is A Finite-element-based Process Modeling Simulation Software

TmmFE_HT: A Practical Approach to Quench Heat Treatment Simulation.

• TmmFE_HT is a finite-element-based process modeling software developed over the past 25 years. It has two specialized modules tested extensively in laboratories and industries related to quench heat treatment. The software is designed with the plant engineer in mind with the theory of heat transfer and metallurgical transformation working in the background. The shell of the software and the interface ensures smooth running of the software with inputs in practical terms.

• TmmFE_HT is for both (i) Metallurgical Engineers in industry and (ii) Researchers in Process Engineering and Mathematical Modeling

• TmmFE HT architecture ensures a well-suited solution for shop-floor oriented users as well as for research experts
