Release improves on multiphysics technology

Software release provides advances in performance, ease-of-use, interoperability and coupled physics technology, such as fluid structure interaction.

Ansys has announced version 10.0 of its Ansys software.

The release provides advances in performance, ease-of-use, interoperability and coupled physics technology, such as fluid structure interaction (FSI).

With availability beginning in July, this release builds on and is compatible with version 9.0.

Continuing to improve upon its multiphysics technology, Ansys 10.0 offers better capabilities for complex FSI problems.

It uses each of the best-in-class technologies in stress and fluid flow analysis.

A single geometry is used for both, with meshing appropriate to the specific physics required.

A high-speed protocol provides the communications necessary to perform dynamic FSI analysis.

It parallelises on multi-machine clusters for very large problem sizes.

"Ansys 10.0 represents the latest in integrated CAE capability, building on the significant advances we delivered in Ansys 9.0", said Jim Cashman, President and CEO at Ansys.

"We have continued to increase the breadth and depth of the Ansys simulation technology, while at the same time establishing an unprecedented level of interoperability between all forms of simulation and analysis".

"Taking full advantage of the Ansys Workbench infrastructure for integrated CAE, we have created a more seamless approach for meshing and modelling, simulation and analysis, and post-processing".

"Our world-class capabilities in each of the forms of analysis such as structural, thermal and fluids are all together as part of Ansys 10.0".

Strengthening the industry-specific Workbench capabilities, Ansys introduces design tools for rotating machinery and blade design.

Ansys 10.0 features Ansys Blade Modeler, a 3D rotating machinery design tool for bladed components, and Ansys Turbogrid, a hexahedral meshing tool for blade design.

"Combined with Ansys CFX and specialised turbo pre- and post- processing CFD capabilities, this creates a comprehensive set for turbomachinery design and analysis", said Chris Reid, VP and General Manager at Ansys.

"Models for stress analysis, computational fluid dynamics or fluid structure interaction can be created, expanded to include upstream and downstream components via CAD system connectivity, and then fully analysed".

"Ansys Workbench is a unique environment to provide for this, such that the aerodynamics engineer can perform CFD-intensive design, while also confirming the structural characteristics".

"This offers the potential for significant reduction in design cycle times".

In the mechanical application area, version 10.0 includes thermal transients, fully implemented within Ansys Workbench.

This lets users perform sophisticated time-based simulations while the Workbench integration automates many of the model setup and solver tasks.

The result is a fast and easy-to-use way to study a product's thermal performance over the expected operating time.

To address the broader need for efficient and timely execution of analysis problems of ever-increasing size and complexity, the 10.0 parallel solver supports choices in communications technology and processors.

In addition to Ethernet and Gigabit Ethernet, it supports Myrinet and Infiniband.

This allows for clusters of high performance at significantly less cost than previous configurations.

Workbench is supported on Windows XP 64bit for AMD and EMT64 chipsets.

This support eliminates the 2Gbyte memory limit that many users face when running large models on Windows.

Extra physical memory can be added to complete the entire design without writing to the hard disk - usually the source of extended computation times.

This enables large model sizes, such as those found in low-frequency static and full transient electromagnetic analyses, to be addressed more efficiently and economically.

The parallel solver supports these physics so it can address large electromagnetic sizes above 100 million degrees of freedom.

In the area of high-frequency electromagnetics, a modal port definition is available.

This simplifies the model setup for transmission line ports needed for many types of IC, RFID and RF MEMS device analysis.

Benchmarks show typical reduction in model size resulting in a 30 to 50% reduction in time and memory requirements for a given model while still providing more accurate frequency-dependent results.

This version also includes the addition of gyroscopic effects that enhance the performance for rotor dynamics application of turbomachinery and other rotating structures.

In the area of direct-coupled field physics, structural-thermal-electric coupling has been enhanced to include thermoelastic damping, an internal loss mechanism in metals, ceramics and MEMS (resonator beams).

"Ansys 10.0 represents another significant step forward for Ansys, within each of the physics domains, and in the way they can be used together in the Ansys Workbench", said Mike Wheeler, VP and General Manager at Ansys.

"No other company in the world of CAE can match the comprehensiveness of our software set or provide the same level of integration in a single CAE environment".
