Numerical simulation for the power generation sector

The power generation sector is subject to deep transformations linked to the implementation of sustainable development strategies and the emergence of renewable energies. Industrialists choose to focus on innovative technological solutions and Transvalor anticipates these developments by offering high-performance software for the simulation of material forming processes. Our solutions with high added-value meet the challenges of the nuclear, petroleum and wind mill industry in terms of quality, time to market and cost savings.

We help you with getting a head start in a highly competitive sector.
031-press-1

Master the manufacture of large parts

In open-die forging, have a reliable and robust manufacturing process to ensure that your production means have the capabilities to make large parts such as rotors, gas turbine shafts or rolled rings.

Work on optimized and less energy-consuming sequences

Thanks to simulation, optimize the sequences of deformation in forging or ingot size and thus reduce cycle times, the quantities of materials used as well as the duration of heating in the furnace.

Manufacture parts in compliance with safety standards

For an ultra-sensitive sector such as nuclear, it is fundamental to be able to master the metallurgy of parts by detecting the segregation and carbon concentration problems and anticipating the hydrogen embrittlement phenomena.

We meet your challenges

For forged components

FORGE® is successfully used by various players of the energy sector. A large range of components can be simulated including rotors, forged shafts, pinions and gears, but also seamless tubes for the oil and gas sector and rolled rings for the wind sector.

For open-die forging, the software has unique functionalities to simulate processes such as upsetting, cogging, etc., and for seamless tubes it simulates hot rolling with mandrel. FORGE® has  a two-mesh algorithm to significantly reduce computation time for processes with incremental deformation.

Thanks to a ‘Multi Pass File’, all the movements of the part imposed by the manipulators, displacements and rotations, can easily be setup, and the simulation of all the steps is handled in a unique launch.

FORGE® is a leading solution for the simulation of hot-, warm- and cold forging processes.

For cast components

THERCAST® is perfectly suited to the requirements of foundries involved in the energy sector whatever the metal used (steel, stainless steel, grey cast iron, lamellar graphite cast iron, ductile cast iron, etc.). The software simulates all types of casting technologies including sand casting, shell mold gravity casting, centrifugal casting, which are generally recommended for the manufacture of large parts such as valve bodies for the oil and offshore sector.

THERCAST® also has many specific functionalities for ingot casting such as the prediction of air gaps or voids and the simulation of exothermic powders. Air gaps dynamic detection is essential because this phenomenon can be the cause of many internal or surface defects.

One of the key advantage of THERCAST® is its ability to simulate each step of your casting process and then offer the complete simulation from the casting to the forging. This is achieved thanks to a coupling between the 2 Transvalor’s codes, THERCAST® and FORGE® which share the same architecture and data management. Results at the end of the casting process can be tracked during the subsequent forging operations. Thus, you can follow the segregations evolution and the porosities closing rate to decide the best manufacturing process according to the open-die forging or ring rolling sequences.

For heat treatment of metal parts

Transvalor offers its SIMHEAT® simulation solution dedicated to heat treatment for a wide range of metal alloys. For massive or large parts, the heat treatment stage is overriding to ensure the expected mechanical properties while controlling distortion phenomena.
SIMHEAT® makes it possible to address both heat treatments in the mass (quenching, annealing, tempering, etc.) and surface heat treatments (carburizing, nitriding, etc.).

SIMHEAT® simulates the heat treatment processes of metal alloys and have a clear vision of the observed distortions on parts, residual stresses and microstructural evolution.

The software allows to take into account variable boundary conditions to faithfully reproduce all the phases during which the parts are quenched or subjected to vertical cooling by sprays.

For microstructure evolution

Transvalor offers an industrial solution to simulate the microstructure evolution during hot deformation processes at the meso-scale, i.e. at the scale of the grain.

DIGIMU® works on Representative Elementary Volume (REV) and it generates digital polycrystalline microstructure representative of heterogeneities of the material. It is based on a full field approach to simulate local and homogeneous phenomena that cannot be captured by higher order models.

Transvalor offers an industrial solution to simulate at the grain size, the microstructural evolutions occurring during thermomechanical and heat treatment processes of metallic alloys.

DIGIMU® is coupled with FORGE® to recover the thermo-mechanical history of the forming process. For monophasic metal alloys, the software models growth phenomena, static and dynamic recrystallization, and also Zener pinning effects due to second phase particles.
