Ansoft Designer~=HFSS?

ansoft hfss free download

1) I'm downloaded Ansoft Designer SV 11.5 version from www.ansoft.com
recently. Is it another name for HFSS?

2) And i'm newbie with the above simulator, anyone have these tutorial? Because
now i'm doing microstrip antenna in design.


Thanks in advance.

1)Ansoft Designer is different from Ansoft HFSS. It contains circuit and system analysis as well as a 2.5 dimensional EM simulator which uses Moment method, while HFSS is a 3 dimensional EM simulator which uses Finite Element method.
2) Ansoft has its own tutorials which are good enough. I propose that you use its "getting started" for Ansoft Designer

Designer is different from HFSS , HFSS is High Frequency Structre Simulator which is a high-performance full-wave electromagnetic(EM) field simulator for
arbitrary 3D volumetric passive device modeling that takes advantage of the
familiar Microsoft Windows graphical user interface. It integrates simulation,
visualization, solid modeling, and automation in an easy-to-learn environment
where solutions to your 3D EM problems are quickly and accurately obtained.
Ansoft HFSS employs the Finite Element Method(FEM), adaptive meshing, and
brilliant graphics to give you unparalleled performance and insight to all of your
3D EM problems. Ansoft HFSS can be used to calculate parameters such as SParameters,
Resonant Frequency, and Fields. Typical uses include:
Package Modeling – BGA, QFP, Flip-Chip
PCB Board Modeling – Power/Ground planes, Mesh Grid Grounds,
Backplanes
Silicon/GaAs - Spiral Inductors, Transformers
EMC/EMI – Shield Enclosures, Coupling, Near- or Far-Field Radiation
Antennas/Mobile Communications – Patches, Dipoles, Horns, Conformal
Cell Phone Antennas, Quadrafilar Helix, Specific Absorption Rate(SAR),
Infinite Arrays, Radar Cross Section(RCS), Frequency Selective
Surfaces(FSS)
Connectors – Coax, SFP/XFP, Backplane, Transitions
Waveguide – Filters, Resonators, Transitions, Couplers
Filters – Cavity Filters, Microstrip, Dielectric
HFSS is an interactive simulation system whose basic mesh element is a
tetrahedron. This allows you to solve any arbitrary 3D geometry, especially those
with complex curves and shapes, in a fraction of the time it would take using
other techniques.
The name HFSS stands for High Frequency Structure Simulator. Ansoft
pioneered the use of the Finite Element Method(FEM) for EM simulation by
developing/implementing technologies such as tangential vector finite elements,
adaptive meshing, and Adaptive Lanczos-Pade Sweep(ALPS). Today, HFSS
continues to lead the industry with innovations such as Modes-to-Nodes and Full-
Wave Spice™.

Oic, Thanks all. Then, Where can i download the Ansoft HFSS simulator? Because i'm need it to do the simulation on patch antenna.

Thank for helping hand.

There is no free version of HFSS.
