ANSYS Releases HFSS 12.0 Engineering Simulation Software
Industry-Standard RF & Microwave Simulation Solution Delivers
Significant New Domain Decomposition Technology for High-Performance
Computing
SOUTHPOINTE, Pa., Sep 17, 2009 (BUSINESS WIRE) -- ANSYS, Inc. (NASDAQ:
ANSS), a global innovator of simulation software and technologies
designed to optimize product development processes, today announced the
release of HFSS(TM) 12.0 software, the industry-leading technology for
3-D full-wave electromagnetic field simulation. The product, part of
the Ansoft suite, helps engineers design, simulate and validate the
behavior of complex high-performance radio frequency (RF), microwave
and millimeter-wave devices in next-generation wireless communication
and defense systems. A key high-performance computing (HPC)
enhancement, domain decomposition, allows engineers to simulate and
design at a scale and speed never before possible. Users of this latest
version of HFSS software can achieve a dramatic reduction in
development time and costs while at the same time realizing increased
reliability and design optimization.
With the release of HFSS 12.0, ANSYS follows through on its commitment
to deliver technology with unequalled depth and unparalleled breadth.
HFSS 12.0 is a major step forward for three-dimensional full-wave
electromagnetic field simulation. The software includes key updates in
mesh generation, solver technologies, and enhancements to the user
interface and the modeler. A new, faster and more robust meshing
algorithm generates higher-quality, more efficient tetrahedral meshes.
The most significant solver technology enhancement is domain
decomposition, a technique that allows HFSS to exploit HPC capabilities
to solve electromagnetic field problems of unprecedented size and
scope. Other important enhancements include mixed element orders,
curvilinear elements, and adjoint derivative computation. Ease of use
and automation in the user interface have been improved and include
additional modeler capabilities such as sheet wrapping and imprinting.
These advances in HFSS 12.0 enable electrical engineers to expand their
solution capability, exploit HPC hardware and fully integrate
electromagnetics analysis into their Simulation Driven Product
Development(TM) processes.
"HFSS 12.0 is a breakthrough in high-frequency electromagnetic field
simulation," said Zol Cendes, chief technology officer and general
manager at Ansoft. "For the first time, engineers are able to solve
vast electromagnetic field problems with speed, efficiency and
accuracy. Because of domain decomposition, microwave and electronics
engineers now have the opportunity to successfully address a new range
of problems containing hundreds of millions of unknowns that previously
could not be addressed by simulation. The ANSYS focus on developing
simulation technology that takes full advantage of modern computer
hardware solutions means that customers will have future capabilities
that, today, we can only imagine."
The new domain decomposition technology in HFSS 12.0 software allows
efficient and highly scalable parallelized simulations across multiple
computer cores including networked cores. In running a 15-GB benchmark
on an HP 7880 workstation, domain decomposition using eight cores
exhibited an 8.8-times speedup with a 33 percent memory savings
compared to a single-core direct solve.
Curvilinear elements and mixed element orders allow for higher accuracy
and more efficient distribution of computational resources. Curvilinear
elements model the fields exactly on curved surfaces and in these cases
provide higher accuracy even with a coarser mesh discretization. Mixed
element orders allows for an automated and judicious localized
application of element order. Smaller features are solved more
efficiently by lower-order elements while large homogenous regions
benefit from higher-order elements, all element orders being
automatically and appropriately "mixed" in one mesh.
Molex Incorporated, a leading supplier of electronic connectors and
interconnect products, was among the organizations that participated in
beta testing the new release. The company investigated a number of
features, including the new TAU volumetric meshing technique, whose
robust tet mesh elements reduce the overall load on the solver. "The
new TAU meshing and mixed element orders technology in HFSS 12.0 will
allow Molex engineers to more accurately and efficiently simulate and
design," said Dave Dunham, engineering director at Molex. "We have more
than doubled productivity with the implementation of HFSS 12.0 in our
design flow."
Adjoint derivative computation provides a highly efficient and accurate
procedure to evaluate the derivatives of S-parameters with respect to
geometric and material model parameter variations. This technique
provides sensitivity information for use in device tuning, tolerance
evaluation and optimization. These derivatives are employed to speed up
the sequential nonlinear programming (SNLP) optimizer included with the
Optimetrics(TM) add-on program.
New features in HFSS 12.0 software include:
* New TAU meshing technology
* Domain decomposition solver technology
* Curvilinear elements
* Mixed element orders
* Adjoint derivative computation
* Update to ACIS R19.2
* Improved link with ANSYS(R) DesignXplorer(TM) software

you can do so during the HFSS software installation.
- Install Remote Simulation Manager: Use this option to install Remote
Simulation Manager on your local machine.
Temp Directory Prompt
---------------------
There is a new dialog in the HFSS installation that prompts you for
a temporary directory to be used by default for all users. You can override
the setting for a specific user by using the Tools > Options > General Options
menu and selecting the Override checkbox associated with the Temp Directory setting.
If you wish to edit the default setting, for now you must modify the installation.
Installation Maintenance
------------------------
If you need to modify the RSM settings after the installation is complete, you
can run the installation in maintenance mode by choosing Start > Programs >
Ansoft > Remote Simulation Manager > Remote Simulation Manager Maintenance.

written out at the highest order used in the solution.
2) Matched terminals
- Users must obtain a build of Ansoft Designer 4.1.1 in order to link with
a driven terminal design in HFSS 12.0.
3) Analytical derivatives
Driven Modal Projects:
- Parameterized ports with degenerate modes
- Parameterized analytical ports
- Parameterized master/slave boundary conditions
4) Remote Simulation Manager
- RSM should not be installed to a mapped network drive.
5) Datalink
- The link to Ansoft Designer will not support post-processing variables for the
HFSS 12.0 release.
