ANSYS unveils new technologies for real world simulation

Keywords: ANSYS, Software, Simulation

ANSYS, Inc. has announced the launch of ANSYS 5.7 (Plate 4) which, in its opinion, represents a significant technical breakthrough in advanced simulation. These breakthroughs are believed to bring users closer to the prediction of real-world conditions and the ability to simulate single as well as complex multi-physical phenomena.

Non-linear analysis is considered one of the most important functions in realistically simulating today's demanding product environments. Knowing precisely how product designs will perform during the manufacturing and assembly processes, and the subsequent product life cycle – before building physical prototypes – can save a tremendous amount of time and money. Moreover, such strategic product designs will result in reduced equipment downtime and greater customer satisfaction.

Traditionally in a finite-element analysis all input parameters such as material properties, geometric extensions of a component, external loads and boundary conditions are regarded as deterministic and fixed values. In reality, however, almost all of these input parameters are subjected to scatter and show variations from one component to another. With the new Probabilistic Design System (PDS) in ANSYS 5.7, these input variations can reportedly be taken into account and their effect on the analysis results can be quantified. This allows the user to address how products behave under real-life conditions. It also allows users to quantify as well as to optimise the reliability and quality of a product in order to achieve a much more affordable design.

Parallel performance for ANSYS introduces both a scaleable shared memory parallel solver and a distributed memory solver. The shared memory solver uses the new algebraic multigrid (AMG) solver, while the distributed memory solver uses the distributed domain (DDS) solver. Both solvers are expected to scale significantly better than their predecessors and will also provide the basis for significant scaling improvements in the future.

"As the engineering industry adopts multiprocessing, not as a luxury but as the norm, parallel performance for ANSYS will enable engineers to solve complex and large engineering systems quickly and affordably", said Paul Bemis, vice-president, ANSYS, Inc. "parallel performance for ANSYS provides engineers with decreased time to completion and the option of using either multiprocessing servers or a cluster or workstations networked together. As multiprocessing becomes more and more prevalent, parallel performance for ANSYS and its AMG and DDS solvers will become the workhorses of engineering simulation".

Key features claimed are:

• •

  Advanced thermo-mechanical contact allowing the fast and accurate prediction of designs containing friction, heat sources, and other related behaviour.

• •

  Enhanced material models for the detailed study of hyperelasticity, plasticity and viscoplasticity-related designs.

• •

  A new advanced probabilistic design system (PDS) developed specifically for providing users with statistical representations of product life, maintenance requirements, and quality predictions.

• •

  Advanced parallel solvers for the fast calculation of extremely large complex simulations exceeding 10 million degrees of freedom and previously prohibitive in terms of time to complete.
