ANSYS 13.0 Puts Emphasis On Performance, Simulation Fidelity  

ANSYS 13.0 Puts Emphasis On Performance, Simulation Fidelity  

ANSYS has announced ANSYS 13.0, the latest release of its simulation software suite featuring an array of new capabilities designed to compress design cycles, optimize multiphysics functionality and maximize the accuracy of virtual prototypes.

New solver methods incorporated in ANSYS 13.0 deliver greater fidelity, helping engineers perform simulations with more accurate results reflecting changing operating conditions over time. For example, a new HFSSA GB pound transient solver for dynamic electromagnetic simulations such as broadband and radar incorporates automatic adaptive mesh refinement and a local time-stepping procedure to accurately represent the geometry and fields while optimizing runtime, stability and efficiency. In addition, a new hybrid solver bridges finite element and integral equation methods for high-frequency electromagnetics problems, a match for applications that combine simulation over a large distance-for example, antennas--with detailed features and complex materials such as computer components.

In the structural mechanics arena, 3-D rezoning can be used for applications that involve large shape deformations, allowing engineers to stop their simulation as their mesh becomes distorted-then remesh the material's current state and continue the simulation. For modeling turbulence in fluid environments, an embedded large eddy simulation (LES) solver delivers speed yet maintains accuracy, applying LES to complex areas of interest and faster-solving Reynolds average Navier-Stokes (RANS) to the rest of the solution. ANSYS 13.0 also introduces a new fluid dynamics capability for multiple reference frames, which enables engineers to model multiple moving systems simultaneously - for example, the rotation of wheels as a car moves around a corner.

ANSYS 13.0's new adaptive architecture makes it easier for users with different engineering specialties to develop real-world simulations that incorporate multiphysics and to collaborate and exchange data. Integration with Microsoft Excel enables users to interact with spreadsheets that contain analytic representations of models and parameter table definitions. Other enhancements include a cutcell meshing feature that produces nearly all hexahedral elements on complex 3-D geometry automatically, an external data mapper that imports data in the form of a column text file defining a point cloud, and tighter integration among the Maxwell, HFSS and mechanical solvers when performing electromagnetic-thermal-structural simulations.

In the area of performance, ANSYS 13.0 incorporates new speedup ratios that are dramatically greater than previous releases of the software. Power enhancements include a new and unique application of variational technology that reduces solution time by a factor of five to 10 when applied to harmonic analysis, officials said. The latest ANSYS release also features greater support for GPU processors.

Finally, ANSYS 13.0 supports the company's vision of making multiphysics simulation tools accessible to a wider range of users. The suite delivers fluid and structural simulation tools for turbomachinery design and analysis; new models for internal combustion (IC) engine applications; and new process and energy industry solutions, including multiphase, real gas, nucleate boiling and chemical reaction tools. Meshing, element modeling, more-tightly coupled fluid-structure interaction (FSI), nonlinear functionality and other improvements round out the enhancements in the 13.0 release which will be available for customer download later this year.
