Ansys HFSS

Excellent Software tool for electromagnetic simulations

Avantages :

I've tried different electromagnetics simulation software like ADS, CST, and FEKO but I felt HFSS is the best. I've been using HFSS software for almost 5 years now, I design Antennas, filters, and RF-related stuff using this software. This is so user-friendly software and can be learned so quickly, a powerful solver for 3D simulations. The accuracy of the simulated results is very good. HFSS documentation is excellent, it includes every detail of the features in the software. The parametric setup in this software is so powerful. The design examples and the documentation included in this software helped me a lot to understand some concepts .

Inconvénients :

The cost of the software is too expensive. I've faced one issue with this software so far, the simulated results are not so accurate when I use high-dielectric materials (DK>10) in my designs, also it takes lots of time to simulate large structures, apart from this I have nothing to dislike.

Ansys HFSS Review

Commentaires : Overall i recommend Simulation Engineers to use Ansys HFSS

Avantages :

GUI, Interface, Easy to use, Documentaion.

Inconvénients :

License are bit costly and installation takes lot of time.

HFFS as a EM simulation companion

Commentaires : so far I'm happy with the software. if the simulation setup can be made easier it's even better.

Avantages :

HFSS is a powerful simulation software which is very useful for EM simulation.

Inconvénients :

Setting up the simulation environment is complicated, especially setting ports for simulation.

Ansys HFSS Product Review

Avantages :

Ansys HFSS is a widely recognized and highly regarded software tool for simulating and analyzing high-frequency electromagnetic fields. Few aspects that need to be highlighted: Accuracy and Reliability, User-friendly Interface, Integration with other tools

Inconvénients :

It may require some time and effort to be proficient in using HFSS.

Developing microwave frequency plannar antenna

Commentaires : I used this program as a student developing plannar antennas in 10-30 GHz range. Really powerfull program, but you need to know about EM topic before.

Avantages :

HFFS is really powerful tool for designing high frequency devices in EM field. It has really good mathematical performance to count wave amplify or attenuation. Also documentation is well written.

Inconvénients :

It is quite expensive program, but for development one of the best.

Good ROI with Ansys HFSS

Commentaires : I work on EMC , SI and PI problems. I use HFSS 3D layout to analyse PCB level SI PI problems and Ansys HFSS 3D for system level EMC Analysis. I find it useful in using analysis at several levels to do quick what if analysis at several levels. However it is yet to reach at per the expectations of system level EMC analysis of very large structures such as an electric vehicle.

Avantages :

The software is very good for Antenna related problems. The accuracy of S parameters are very good compared to other software. The latest feature of mesh fusion using HFSS component is very useful in solving large scale problems in EMC or SI. Integration with current business process is not very easy due to time gap when problems are discovered.

Inconvénients :

Fast solvers are required for sparse matrix manipulation and speed up the simulation. Script work flow for emc simulation would be highly effective for integrating with hardware design process. The need for fit to use virtual laboratory of emc analysis would be very useful in virtual prototyping of design processes.

Review for HFSS

Avantages :

It's a powerful group of users. Once it has become a standard in this field as an S/W with a long history and many users, numerous application cases, interpretation techniques, and verification materials are unrivaled.

Inconvénients :

If it is a disadvantage, FEM itself is an old theory, so there is a limit to improvement, and it can be seen that HFSS has reached a certain limit in terms of speed, accuracy, and application.The fact that users can get accurate results only when they properly learn and use the mesh control method, and HFSS uses the FEM method based on frequency domain, so there are many difficulties in calculating broadband frequency.

EM Simulation with time and money saving

Avantages :

The tool is very suitable for performing close to real performance EM Simulation. The help section os very great. The documentation is like spoon feeding the beginners. Report generation is very simple for the simulation results. This software offers a lot of flexibility. The features are great as compared to competitors.

Inconvénients :

The software GUI needs an update and looks outdated. The video section still needs additions. The area of bi-static radar cross section is not discussed in details in help and documentation of the tool.

Crucial for advanced antenna and RF design

Commentaires : My work as an antenna designer would be impaired without Ansys HFSS.

Avantages :

Accuracy of the mathematical methods being used is excellent

Inconvénients :

SBR analysis could be improved. There some bugs in the interface at times.

HFSS is Essential to Our Antenna and Phased Array Developments

Avantages :

HFSS is an essential tool that allows us to achieve first pass success in our antenna and phased array product development. We use it for antenna operating in the 2-40GHz frequency range for both wide band and narrow band solutions. The optimization capability and accuracy of the solutions allow us to achieve required performance without having to perform multiple design-fabricate-test cycles. The result is faster time to market, improved specifications, and lower development cost.

Inconvénients :

HFSS is not a low cost solution, but the results can justify the cost for many product developments.

Good to use

Avantages :

Accuracy is very good. Also quite powerful solvers for 3D simulations.

Inconvénients :

At start, it is quite difficult to get used to with

Learning rf and microwave with Ansys HFSS

Commentaires : I have used ANSYS HFSS student version. The experience was very nice. I designed antennas, filters, couplers/power dividers, and matching networks. I always recommend HFSS to anyone who wants to learn industry specific software for RF and microwave.

Avantages :

The most impactful feature of the ANSYS HFSS is the FEM technique used for the solution. This requires one to understand different concepts of electromagnetic before someone uses it. And, ofcourse the Ansys HFSS documentation is great. It has everything.

Inconvénients :

The least thing I like about this software is that it takes lots of time to simulate electrically larger structure. Therefore, I think we need to look into this side so that ANSYS HFSS simulation goes faster for electrically larger structure.
