Altair Engineering, Inc. today announced that Airbus, one of the world's leading aircraft manufacturers, has chosen Altair’s OptiStruct advanced topological optimization software for the A350XWB program. Airbus pioneered the use of topology optimization in aircraft design, and, during the A380 development, used OptiStruct for design optimization to support weight reduction. Based on its experience with the A380 program, Airbus has now selected OptiStruct as the strategic tool for topological optimization for their development projects.
