Ansys HFSS Reviews & Product Details

I like Ansys HFSS for its accuracy and reliability in electromagnetic and antenna simulations, especially for product-level analysis. HFSS helps me understand how an antenna behaves in real-world conditions when integrated inside an enclosure or complete device. The radiation pattern, gain, efficiency, and impedance matching results are very close to practical measurements, which helps reduce prototype iterations and development time.

One area where Ansys HFSS could improve is the simulation time and computational requirements for large product-level models. When simulating complete devices with multiple antennas, shielding structures, and detailed components, the simulation can become very time-consuming and requires high-end system resources such as large RAM and powerful processors. Another challenge is the meshing process for complex geometries. Sometimes achieving proper mesh convergence takes multiple iterations and manual tuning, especially for electrically small structures or very detailed models. This can increase overall development time. Review collected by and hosted on G2.com.

It is a full wave solver, easy to use, and has great visualization options. It can also implement complex structures. The customer support is easily available. Review collected by and hosted on G2.com.

It does not offer good model conversion with other solvers like CST, you can import a model but material properties are lost Review collected by and hosted on G2.com.

Not having open source platform to design Review collected by and hosted on G2.com.

The graphical interface for object making is very good in HFSS full-wave Electromagnetics simulation. The control of the object is very good. Furthermore, the simulation of results has very good agreement with real measurement. Review collected by and hosted on G2.com.

The conformal object makes such as I have used this during my Ph.D. research. The HFSS has not provided a predefined section for conformal or flexible objects except sheet wrap which is sometimes very much problematic as we are conforming onto a conical surface or doubly curved surface.

It's the best EM simulation software in the market. It helps in designing and analyzing so many EM parameters. Review collected by and hosted on G2.com.

Nothing as such. Works completely beyond expectations. Review collected by and hosted on G2.com.

I use HFSS for antenna simulations mostly. I am also working on Terahertz sensors and periodic structures. It is easy to simulate unit cells and replicate results for arrays.

I like the easy conversion of file format for the fabrication process.

I simulated a semiconductor that has frequency-dependent permittivity and had to use the Drude model. It was easy to load the data point in HFSS for material definition. Review collected by and hosted on G2.com.

I felt there is a lack of resources for a new user on how s/he can start. There should be more quick start guide.

While simulating semiconductors, I felt other than loading the data points; there should be a predefined model for The Drude and Lorentz theory Review collected by and hosted on G2.com.

I liked most the ease with which we can design Antennas and simulate their EM effect and also designing antenna arrays are way easier. There are great benefits of Ansys as I am an Antenna Designer. I usually design Antennas in HFSS before going for the fabrication process. HFSS helps me to analyze antenna parameters properly and how this antenna will perform in the real world and if changes are required, we do it in Ansys rather than going straight to fabrication. HFSS is one of several commercial tools used for antenna design, and the design of complex radio frequency electronic circuit elements including filters, transmission lines, and packaging. It was originally developed by Professor Zoltan Cendes and his students at Carnegie Mellon University. Review collected by and hosted on G2.com.

Depends on what kinds of problems you are trying to solve. For certain nonlinear problems with complex geometries, using Ansys software is difficult.

The user interface and tools accessibility of the ANSYS HFSS is really helpful while creating a new unique model. For my project, I was able to create a unique model of a planar antenna and simulate to find out the S parameters for the different changes I made in the design.

RAM usage, while doing the simulation I faced a lot of crashes in between. Also, when simulating the same design on two different computers, I noticed a few mismatches in the results. I was able to create different designs, and in my designs, I had to make a lot of slits for my antenna as part of my research, but each time I had to insert another slit-shaped object and perform the subtraction to get the slit. At that time, I felt the need for an extra tool that could be used to cut out the shapes needed for the main design. Review collected by and hosted on G2.com.

Creating the structure and applying boundary conditions is very easy and straightforward. It has a project tree that I like very much, and the meshing is very good, although not the best. Review collected by and hosted on G2.com.

It can provide more examples and a better website for some sample simulations. It can also be updated with more boundary conditions and especially more excitation methods like dipole source excitation. It would also be nice if Ansys could investigate more in optical simulations as well as EM in the microwave domain. Plus, it can introduce a programming part not the one with MATLAB but an easy one like the way Numerical does. Review collected by and hosted on G2.com.

I like that I was able to perform analysis on my designs while still in the conceptual stages so I didn't waste time on a design with structural weaknesses. Review collected by and hosted on G2.com.

I thought it was rather cumbersome to set up and get going at first but after some time you get used to it. Review collected by and hosted on G2.com.
