Ansys HFSS Reviews

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.

It does not offer good model conversion with other solvers like CST, you can import a model but material properties are lost

I have used

Implementation and Analysis of micro level design

Not having open source platform to design

I stuck in my project where I required patch antenna which is not in stock in local market in COVID day's, I designed same patch antenna with this software and resolve my ongoing projects multiple times.

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.

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.

The conformal wave port has used the simulation of an antenna array which must be outside of the radiation boundary.

It's the best EM simulation software in the market. It helps in designing and analyzing so many EM parameters.

Nothing as such. Works completely beyond expectations.

It is helping me find out different RF characteristics of many electronic equipments.

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.

High accuracy results and speed of simulation are what I like more about this CAD software.

In my humble opinion it has uncomfortable drawing and edition 3d elements process. There is not (or wasn't at least) a comfort parametrical design (like in CST).

It is accurate and fast EM simulation tool which allows you to obtain valid result even without special hardware acceleration: GPUu's and so on.

I mostly used it for printed, horn and wired antennas and microstip filters simulation.

I liked most the ease with which we can design Antennas and simulate their EM effect amd also designing antenna arrays are way easier

There are great benefits of Ansys as I am Antenna Designer.

I usually design Antenna in HFSS befor going for fabrication process.

HFSS helps me to analuze antenna Parameters properly and how this antenna will perform in real world amd if changings are required we do it in Ansys rather then going staright to fabrication

Highly accurate for closed field design in fact it had been the best solution our research group had at our disposal for the analysis of three-dimensional electromagnetic field analysis.

Computation speed can be a little slow but that could also be a function of the user's system but HFSS, overall, is a bit heavy in the use of system resources.

I was involved in research projects where we were required to design antennas which would later be used in satellite communications by a top research group of the country where our role was to work with the provided specifications but optimise them to achieve the desired gain which required a lot of highly accurate simulations otherwise the costs would've been highly prohibitive and that's where HFSS helped us in delivering what was expected of us while staying within the allocated budget.

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

Ram usage, while doing the simulation I have faced lot of crashes in between. And also when I was simulating the same design on two different computers I was able to see few mismatches in the results. And I was able to create different designs, and in my designs I had to make a lot of slits in for my antenna as a part of my research but for that each time I had to insert an another slit shaped object and had to do the subtraction for getting the slit. At that time I felt the need of an extra tool that can be used to cut out the shapes we needed for the main design.

I have used Ansys for creating planar antenna and get the transmission parameters for the antenna for different design specification and also i have implemented waveguids etc. I have created different design of planar patch antenna with different grounds. Such as i have used circular ground shape , triangle ground shape pentagon shaped ground etc in my design. And also I did few research on putting defects in the ground will affect the transmission coefficient. I was able to see shift in S Parameters for the defects in ground. Created and tested planar antenna for WiFi communication.

I love the user interface easy to use.the software is easy to maneuver. The generated information in a simulation are very detailed and useful on my design.

I don't really have much dislike on the software. It benefit my studies and understanding on my design.

Very useful software

I used it to design different types of antenna to meet my application goal.
