ANSYS Announces Simulation Solution v11.0
 SOUTHPOINTE,
Pennsylvania, February 26, 2007 - ANSYS, Inc. (NASDAQ: ANSS), a global
innovator of simulation software and technologies designed to optimize
product development processes, today announced Version 11.0 of its ANSYS
software. This latest version of the ANSYS family of engineering simulation
solutions offers new and enhanced tools and capabilities that enable users
to complete jobs efficiently and fully leverage Simulation Driven Product
Development for a wide range of applications. This release represents the
leading edge in integrated, best-in-class computer-aided engineering (CAE)
functionality including advanced analysis, meshing, optimization,
multiphysics and multibody dynamics.
The enhancements to ANSYS 11.0 software follow the tradition of making
powerful simulation tools available to an increasingly wider range of
product developers. "As with previous major product releases, we are pleased
that ANSYS continues to deliver according to customer expectations: better
and more expansive tools, all in pursuit of true Simulation Driven Product
Development," says Jim Cashman, president and CEO of ANSYS, Inc.
Continuing its commitment to provide state-of-the-art solutions, ANSYS
introduces new solver technology designed to reduce time when performing
transient solutions. Version 11.0 uses Variational Technology (VT) as an
advanced predictor-corrector algorithm to reduce the overall number of
iterations for nonlinear static and transient analyses. In the CAE field,
this kind of analyses traditionally results in long run times - and has
discouraged users from performing what-if scenarios that might provide
information about how a design performs in the real-world environment. By
reducing the overall number of iterations, ANSYS has greatly reduced the
solution time for nonlinear static and transient analyses. This capability
provides a 2X to 5X speedup for the initial solutions, depending on the
hardware, model and type of analysis used. ANSYS VT Accelerator technology
makes re-solves 3X to 10X faster for parameter changes, allowing for
effective simulation-driven parametric studies of nonlinear and transient
analyses in a cost-effective manner.
In order to provide "innovations that work," Florida Turbine
Technologies, Inc. - which executes all aspects of turbine engine design and
development in the military and commercial aircraft industry - desires
transient fidelity early in the design process. "Due to long run times, we
usually reserve transient analyses for detailed final design," says Joseph
T. Metrisin, lead structures engineer at Florida Turbine Technologies, Inc.
"Faster solution options will allow us to perform detailed transient
analyses early on in the design process, resulting in more robust designs."
The integration of ANSYS and ANSYS CFX technologies in the ANSYS
Workbench platform has taken another step forward. With version 11.0, users
will be able to set up, solve and post-process a two-way fluid structure
interaction (FSI) simulation completely in ANSYS Workbench. The latest
release also provides a single post-processing tool. ANSYS Workbench
significantly reduces the time needed to obtain solutions to complex
multiphysics phenomena.
ANSYS 11.0 has been refined to address some industry-specific needs as
well. In the rotating machinery sector, for example, ANSYS leverages the
power of its advanced fluids (ANSYS CFX) and multiphysics (ANSYS) software,
along with its integration platform (ANSYS Workbench), and combines these
with a partner tool (Vista CC Design) that allows users to develop better
turbomachines in shorter time. The ANSYS Workbench platform provides an
integrated geometry design and analysis system that links all elements of
the design process. It is the integration platform for advanced physics
capabilities in ANSYS CFX and ANSYS(R) BladeModeler that enable designers to
model rotating machinery such as pumps, compressors, fans, blowers,
turbines, expanders, turbochargers and inducers. The integration of all
these ANSYS solutions into the design process can take weeks out of the CAE
process by eliminating manual file transfer, result translation and
re-analysis time. The partner tool, initial sizing software used during the
preliminary design phase, is from PCA Engineers Limited.
The first step in the turbomachinery design process is to obtain a
preliminary design using initial sizing software, given the performance
criteria and sizing constraints. At ANSYS 11.0, PCA Engineers Limited's
Vista CC Design (CCD) initial sizing software for centrifugal compressors
and pumps is included in ANSYS BladeModeler. This is a rapid meanline design
program that - when given the compressor duty mass flow, pressure ratio and
geometric constraints - configures the compressor scantlings, vane inlet and
exit angles, velocity triangles. It also provides essential non-dimensional
performance parameters, such as specific speed and specific flow rate on
which design decisions can be based.
Turbo Solutions Engineering LLC has experience with a broad range of CAE
software. It uses ANSYS solutions to help customers in industries such as
aerospace and HVAC to develop new machines. "The recent addition of PCA
Engineers' Vista CCD and Vista CPD compressor and pump design software into
the ANSYS CFX product line has considerably streamlined our turbomachinery
design process," says Nicholas D'Orsi, partner and chief engineer at Turbo
Solutions Engineering. By using the Vista interface, we can rapidly complete
iterative sizing and performance estimation for centrifugal and mixed-flow
turbomachinery. A key feature of this new interface is the transfer of an
initial impeller three-dimensional design into ANSYS BladeModeler software.
Once inside ANSYS BladeModeler, the analysis features of ANSYS CFX allow for
quick optimization of the design."
Integrating meshing technologies and applications to provide the widest
selection of meshing tools has been a major focus for ANSYS in the past five
years, and the latest release is no exception. ANSYS 11.0 delivers more
examples of meshing technology integration and provides physics-based
meshing solutions that tailor the mesh for mechanical, electromagnetics,
computational fluid dynamics (CFD) or explicit dynamics simulation.
Best-in-class meshing technology from ANSYS, ANSYS ICEM CFD and ANSYS CFX
products has been integrated in the ANSYS Workbench platform to leverage the
strengths of the various algorithms to provide an intelligent, flexible and
robust solution to meshing.
Based on the defined physics filter, various controls are automatically
defined, such as mesh size, mesh transition, mesh uniformity, mesh speed,
mesh quality and refinement controls for proximity and curvature. Advanced
user controls then are available to exert influence over the mesh when
required. This intelligence in meshing allows even the novice user to get a
good mesh suited for the defined physics while providing the flexibility of
additional controls to improve the solution speed and/or accuracy. The
multiple meshing methods, available through advanced options, also provide
backup meshing approaches to improve the overall robustness of the meshing
solution.
Integration efforts now have been applied in the explicit dynamics arena
as well, resulting in a modeling environment for explicit analysis that is
much easier to use and more productive. ANSYS AUTODYN software is a uniquely
versatile explicit analysis tool for modeling the nonlinear dynamics of
solids, fluids and gases and their interactions. At release 11.0, ANSYS
AUTODYN is available for the first time as an integrated tool in the ANSYS
Workbench platform. Tightly coupling ANSYS AUTODYN with tools such as ANSYS
Meshing and ANSYS DesignModeler provides an environment in which rapid
decisions can be made based on results provided only by an explicit dynamics
simulation.
A leading developer and manufacturer of ammunition systems as well as
missile and space propulsion products, Nammo Raufoss AS uses advanced CAE
tools to design and optimize new products. "At Nammo Raufoss AS, we have
found that our preferred explicit dynamics tool, ANSYS AUTODYN, is even more
useful to us now that it is part of ANSYS Workbench at release 11.0," says
Gard Odergardstuen, research and development manager at Nammo Raufoss. "We
are saving significant amounts of time by being able to associatively link
to our CAD models, mesh and solve them all within the ANSYS Workbench
platform. Because we are able to parametrically modify the CAD and re-run a
new simulation with a few mouse clicks, we are now able to use the ANSYS
AUTODYN results to guide our design efforts."
Another significant new enhancement to legacy ANSYS technology allows CAE
users to dramatically cut time spent studying design performance on flexible
dynamic systems. At release 11.0, ANSYS enhances and assembles its wide
array of advanced structural dynamics capabilities, bringing frequency
response and time history of flexible structures and dynamic systems
together. Users now can select a range of behaviors: from linear to advanced
nonlinear fully flexible responses, and all combinations in between, for
their design performance simulations.
At Dale Earnhardt, Inc., engineers use ANSYS tools to analyze racecar
parts and performance for increased power, speed and safety. "In NASCAR, we
are always looking for an advantage that produces a faster and safer race
car," says John Klausmeier at Dale Earnhardt, Inc. "The enhanced flexible
dynamics capabilities we've found in ANSYS 11.0 are helping us understand
what happens to our machines at 200 miles per hour under real transient
track conditions. These enhanced ANSYS tools show us not only where some
components have failed previously, but also why they've failed. Because
ANSYS tools maintain associativity with our CAD vehicle models, fixing the
problem is pretty straightforward once we've discovered what is causing them
to fail."
The goal of the ANSYS focused software development road map is to provide
customers with the most advanced and reliable engineering simulation
solutions available in the industry. Chris Reid, vice president, marketing
at ANSYS, Inc., says, "With ANSYS 11.0, we have continued our track record
of adding significant new and enhanced capabilities to address increasing
complexity and sophistication - simulation requirements that come from our
valued customers as well as the industry in general."
