Ansys tests out optical processing for automotive modelling
Ansys is using laser-based optical processing technology from Lightsolver in Israel for its automotive modelling tool.
It has tested out its LS-DYNA nonlinear dynamics structural simulation software on LightSolver’s optical processing platform to accelerate simulations for automotive, aerospace, and other industries. This will also bring optical processing into the automotive modelling tools from Synopsys which is merging with Ansys in a $35bn deal.
- Europe approves Synopsys merger deal
- Synopsys sells off optical systems group
- Ansys shows autonomous driving tools ahead of Synopsys deal
LightSolver’s all-optical Laser Processing Unit (LPU) uses the interference patterns of lasers to compute large and complex problems, faster and more efficiently than the most advanced classical high performance computing (HPC) systems. The LPU is suited to computations that require massive amounts of iterations, such as optimization problems and simulations in computer-aided engineering (CAE).
Today, LightSolver offers a digital platform that emulates LPU functionality and accelerates computations for certain use cases. Ansys used this to explore several mechanical analysis cases to reduce floating point operations and storage. The test showed that the combination can shorten product development cycles, ultimately delivering more accurate design insights and reducing costs for companies that use complex engineering models.
But the company is building an all optical supercomputer with cloud access.
Multiphysics simulations, such as computational fluid dynamics (CFD) and finite element analysis (FEA) often require the calculation of dynamics for billions of grid points across many time steps. In the cases tested, LightSolver successfully optimized sparse matrix reordering within the Ansys LS-DYNA solver, reducing the amount of computation required and ultimately enabling faster run times.
