GeonX News & Achievements
13 November 2017: Selective Laser Melting simulation of the ENGIE functional part Twister using Virfac®
21st March 2017: GeonX can predict the melt pool geometry and porosity after solidification through a multiphysics simulation
14th January 2017: GeonX collaborates activelly with Beam Machines and IREPA Laser to develop powerful and predictive models of the Laser Melting Deposition.
June 2016: GeonX is proud to announce the official release of Virfac® 1.4 including a major new feature: Virfac® Additive Manufacturing. This module allows predicting distortions, residual stresses and potential defects during the Selective Laser Melting (SLM) of complex industrial parts.
April 2016: GeonX has developed a new module in Virfac® which allows the user to easily and automatically simulate the Selective Laser Melting (SLM). Based on the process parameters, the simulation provides the deformation amplitude of the printed part as well as the residual stresses and plastic strains. In partnership with Sirris (Belgium), Geonx has validated its technology successfully, comparing numerical predictions with the experimental measurements.

August 2015: In partnership with Optimal Computing, GeonX is developing a new utility module in Virfac® Welding which allows the user to easily and automatically calibrate parameters of an equivalent heat source. Using a workpiece macrograph and/or temperature plot, Virfac® provides an optimized set of parameters for representing the best suited heat flux for modelling the welding process. The methodology is using an inverse analysis based on the powerful optimization engine of Xtreme software coupled with Virfac® solver Morfeo®. This new tool is planned to be released in the next version of Virfac®.
May 2015: GeonX S.A. has joined the Altair Partner Alliance (APA), bringing access to Virfac®, its welding simulation software, to HyperWorks® users. Virfac® provides quality predictions for manufactured parts with the ability to improve product lifespan and design before any prototype is required.
May 2015: GeonX is pleased and honoured to announce DCNS (France) as a new customer. DCNS selected Virfac®, the Virtual Factory simulation software of GeonX, to address its advanced welding simulation challenges. DCNS represents the first client of GeonX in the shipbuilding sector.
December 2014: This simulation of laser transmission welding of a thermoplastic, evaluates the evolution of temperature fields and the resulting melting and resolidification during the process. It can be used to evaluate the quality of welding as a function of the process parameters.
November 2014: This simulation follows the distortions in a steel gear as it is quenched from 900°C to less than 300°C in five minutes. The material in the gear teeth is the first to cool down to the Martensite start temperature and transform to Martensite. The change in volume applies a stress on the inner parts that is still Austenite, and gives rise to distortions in this region.
September 2014: This simulation follows the flow movement of particles during the Friction Stir Welding process. Virfac® predicts the resulting energy generation due to friction and large strain rates effects. The results from the thermo-fluid analysis are used as boundary conditions in a transient thermo-mechanical simulation.
August 2014: Discover the first video describing the features of Virfac® Welding. GeonX has generated the first live demonstration on a Caterpillar-type Excavator. The workpiece is 7 m long and one weld is represented. The FE model includes a transient thermo-mechanical analysis. The simulation is parallelized on 12 processors.
July 2014: GeonX has a joined an international benchmarking in advanced welding simulation. Virtual welding of a T-Joint made of DH36 with Virfac®.An advanced naval application. The workpiece rests on two cylinders. The FE model includes contact management between the workpiece and the support system. The simulation is parallelized on 12 processers.
February 2014: An example of Transient Thermo-Mechanical Analysis accounting for the Elasto-Plastic constitutive law and thermal properties (as a function of temperature) of AH36 steel. Prediction of residual distortions and stresses. Technical characteristics: - Naval application (tanker), - CAD: PARASOLID format (.X_T), - Components: 2 Stiffened Panels, - Dimensions: 3.48 x 16 m, - Thickness: 13 mm, - Weld Length: 16 m.
January 2014: An example of Additive Manufacturing with Virfac® powered by Morfeo. Cladding of a cylinder: external diameter 50 mm, internal diameter 48 mm, length 32 mm. The cylinder is built over a plate 200x200x10 mm. The 14 layers thickness is 1.8mm and the total clad length is 2.20m. This movie shows the results of a purely thermal analysis with 30,000 nodes performed on 16 cores in less than 15 minutes.
December 2013: GEONX and JSOL Corporation (1,300 employees) have signed a fruitful partnership agreement. JSOL Corporation becomes the official retailer of GEONX in Japan, promoting and selling the Geonx Virtual Factory, VIRFAC®. More info at http://www.jsol.co.jp.
November 2013: GEONX is pleased to announce that Mr Emeric d'Arcimoles was elected Chairman of its Board of Directors. More info at Communniqué de presse.
