Simulation Tool Helps Predict and Solve Welding Challenges
TROY, Mich.—Welding simulation software that was recently made available to HyperWorks® users through the Altair Partner Alliance (APA) is reported to help predict and solve challenges encountered in welding and manufacturing processes. HyperWorks users gained access to the Virfac® software from GeonX S.A. in May, when Altair announced that GeonX S.A. had joined the Altair Partner Alliance (APA). According to a press release from Altair (altair.com), Virfac provides quality predictions for manufactured parts with the ability to improve product lifespan and design before any prototype is required.
Virfac is said to be capable of predicting residual distortions encountered by a part during the manufacturing process, as well as residual stresses, to help calculate the in-service fatigue life of the part. Particularly suited for high fidelity results on complex industrial applications, the simulation software reportedly ensures manufactured part quality by predicting material transformations during the process, as well as the final manufactured component.
“Virfac is a new type of technology in the HyperWorks offering, and I believe this will help us identify many different ways to collaborate,” said Laurent D’Alvise, CEO of GeonX, in the release. “GeonX is really looking forward to exploring the possibilities of the partnership with Altair.”
Virfac employs several solvers as computing engines—all dependent on the accuracy level and physics necessary for a particular model—to help the software address a wide range of problems. The main computing engine applied by Virfac is Morfeo, a massively parallel finite element (FE) solver capable of non-linear thermo-mechanical-metallurgical detailed modelling of manufacturing processes. Morfeo performs simulations of various manufacturing processes on high performance computing systems. This connection helps Virfac perform advanced simulation of welding processes, including fusion welding, friction stir welding, and inertia friction welding, and creates the capability to mimic results of various heat and surface treatments, additive manufacturing, and damage tolerance based on the XFEM technology.
“Through its advanced multi-physics, Virfac is able to capture extremely important phenomena in manufacturing processes,” said Subir Roy, senior director of industry solutions at Altair. “Simulating residual stresses and distortions in welding and heat treatment bridges the gap between physical and virtual reality. Altair is eager to bring this technology to its users involved in solving complex manufacturing problems via simulation.”
Virfac is applicable across industries that include automotive, aerospace, heavy industry, shipbuilding, and energy.
