Advanced Solver, Analysis and Simulation Automation Capabilities Improve Ease-of-Use and Simulation Sophistication -- ANSYS, Inc., a global innovator of simulation software and technologies designed to optimize product development processes, has achieved new standards for CAE analysis and simulation with the latest version of its flagship solution that allows more users to apply new advanced physics to real-world engineering problems. ANSYS 8.1 features new high-end simulation capabilities, as well as design process enhancements that enable these advances to be applied more easily and accurately. ANSYS 8.1 includes advances in parallel computing, solver technology, memory management, data handling, electromagnetics analysis, linear and nonlinear analysis, integration, ease-of-use and the solution of advanced coupled physics problems using ANSYS Multiphysics. "Continued development of best-in-class CAE engineering tools remains our focus at ANSYS, and with ANSYS 8.1, we are continuing to expand the boundaries of CAE simulation," said Jim Cashman, president and CEO at ANSYS. "The advanced physics and other improvements in ANSYS 8.1 provide more users with a far more comprehensive simulation and analysis solution for design innovation." ANSYS Workbench Ease-of-Use and Simulation Sophistication ANSYS continues to integrate advanced capabilities into its Workbench Environment, allowing more users across an organization to access advanced simulation tools. Workbench enhancements for ANSYS 8.1 introduce new features for analysis of nonlinear materials and contact problems. The development of automatic contact meshing, convergence and results tracking make it easier to set up and manage these complex applications. The new remote solving capabilities in the Workbench environment allow ANSYS users to manage their hardware investments more efficiently, freeing up their desktops for continued productivity in engineering and other office applications. These applications are all part of the integration of high-end ANSYS features within the Workbench. Advanced computational fluid dynamics (CFD) meshing also has been integrated into Workbench 8.1 with the new CFX-Mesh module. Based on the meshing technology that is part of CFX pre-processing, this robust, new feature now has a new user interface completely integrated with the Workbench approach to simulation. CFX-Mesh utilizes geometry creation and imports through DesignModeler, providing an exceptionally easy-to-use product with the proven high mesh quality CFX users rely on. ANSYS' acquisition of CFX in early 2003 has enabled the company to provide these advanced capabilities to its customers within the Workbench environment. Pushing the Limits of Large-Scale Computing Building upon its distributed parallel solvers, ANSYS continues to lead the way in this area with enhancements that evolve its solvers to handle large-scale analyses with minimum memory usage. Using a minimum memory approach, ANSYS users now have the ability to solve eight million degrees of freedom models on inexpensive 32-bit clusters, providing ANSYS customers maximum productivity with a minimum of hardware. Additional enhancements in memory management and data handling allow for the solution of enormous problems by enabling the solvers to use more than 16GB of memory. Typical application areas include complete analysis of engine blocks for static structural and thermal analysis. ANSYS 8.1 features further improvements in the Component Mode Synthesis (CMS) algorithm, allowing for accurate eigenvalue calculation at the mid- to high-end of the spectrum. These enhancements are ideal for applications like modal analysis of complete automobile or plane models. CMS allows users to break a model into small parts (substructure), run a model analysis on individual parts, and combine them for a complete analysis. These latest enhancements extend the application of CMS for large-scale models when distributed computing may not be practical or available. Advanced Electromagnetics Analysis ANSYS 8.1 features new higher-order electric elements for low-frequency electric field analysis. These elements apply to steady-state electric conduction, time-harmonic and transient quasistatic electric field analyses. ANSYS' existing electrostatic elements also have been extended to harmonic and transient electric field analysis. These advanced features allow electric field analyses that take into account both conduction and capacitive effects with applications to lossy dielectrics, high-voltage insulators, microwave passive components, semiconductor devices, MEMS and biological tissues. ANSYS 8.1 features enhancements in current loading for magnetic elements. These elements are used for low-frequency electromagnetic analysis. With ANSYS 8.1, magnetic elements can take current loading from current source elements, which are mesh-less primitives used for modeling stranded coil analysis problems. These enhancements are designed for electric motor and solenoid analysis applications. In addition, ANSYS 8.1 boasts improvements in high-frequency electromagnetics analysis. Users now can perform phased array antenna analysis, allowing the radiation pattern and directive gain of a single cell or array to be efficiently computed. This feature also allows for a drastic reduction in the problem size and improves solution speed. ANSYS 8.1 also provides enhanced high-frequency mesh refinement tools for improved solution accuracy. Advanced Multiphysics Analysis ANSYS 8.1 includes additional enhancements to the Multi-field solver that make the load transfer and mapping between sequentially coupled physics more robust and efficient, providing faster and more accurate multiphysics solutions. Advanced Linear/Nonlinear Analysis ANSYS also has made enhancements to its modal harmonic analysis capabilities. Users now can specify system damping independent of frequency. Application areas are in analysis of engine mounts with different damping coefficients that produce a constant damping force. Enhancements also have been made to support node-surface contact elements for multiphysics analysis through electric, magnetic and thermal contact. These capabilities are ideal for modeling thermal, electric resistance of assemblies and structures. Additional enhancements have been made in contact setup through a partial solution for initial configuration and nonlinear diagnostics for convergence.
