Ansys HFSS Reviews & Product Details

Implementation and Analysis of micro level design 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 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

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 problem with complex geometries, using Ansys software is difficult

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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

Creating the structure and apply boundary condition is very easy and straightforward. It has a project tree that I like it very much and also 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 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.

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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

1- After fabrication of the product you would get very accurate results quite similar to what you had simulated. It is extremely accurate.

2- Wide range of simulation and post processings which makes it easier to get what you need.

3- Integrity of the products, you have access to the different simulator for different purposes while they would easily communicate with each other which make it faster get the design done.

4- Cloud computing, offering simulation on HPC make the simulations quite fast while you do not need to worry about the server maintenance. Review collected by and hosted on G2.com.

1- Setting up cloud computing (HPC) required a bit of IT knowledge and is not straight forward.

2- It's hard to work with complex meshes in HFSS. The user 3D interactions and the tools need to be improved.

3- Again related to the 3D environment it is hard to draw an object quickly and accurately take a lot of time for developing a model. Review collected by and hosted on G2.com.
