Comparing HFSS, CST, and CENOS™ radio frequency simulation software

There are several RF simulation softwares that engineers can use to work on their projects (HFSS, CST, FEKO, to name a few). Compared to the CENOS™ radio frequency simulation, which one to choose?

See how CENOS compares to best simulation software in the market

We've heard that engineers often lack the resources to conduct thorough studies to determine the best simulation software for their projects. They often opt for the most popular option, which can be overwhelming and often quite expensive.

 

CENOS™ RF simulation software is easy and quick to learn, and it gets the job done. CENOS™ also offers free onboarding to ensure you get your results right away. CENOS™ is dedicated to helping engineers around the world use simulation software at an affordable price and with a very low learning curve.

CST Studio Suite is a powerful 3D EM analysis software to design, analyze and optimize electromagnetic (EM) components and systems. CST Studio Suite is used in leading technology and engineering companies around the world.

 

Ansys HFSS is a versatile 3D electromagnetic simulation software (EM) for the design and simulation of full-wave high-frequency electronic devices such as antennas, components, interconnects, integrated circuits (ICs), and printed circuit boards (PCBs).

EASE OF USE

& TRAINING DURATION

Exceptionally easy to use, self-service learning in a couple of days

Needs months-long education and training

CAD LOADING EXPERIENCE

Easy step file import, intuitive one-click role assignment for RF parts & boundaries

Allows import of native CAD formats, but require long set-up process

HOW IS CENOS DIFFERENT?

All you need from one
simulation software

 

Main areas of the CENOS™ RF

Create simulations for application groups such as microstrip, horn, reflector, wire antennas, and waveguides. Study the ideal placement of an antenna in a device to ensure maximum radiation pattern in the least amount of space. Use powerful visualization tools to share and analyze various RF designs with colleagues and partners.

CAD file support

A user of CENOS™ RF simulation software can easily upload CAD (step) files. In the majority of cases, the mesh is created automatically. Recent tests by our engineers have shown that 75% of all CAD fields are successfully meshed automatically, only the remaining 25% need to be meshed manually.

Recalculation and analysis

​All settings are kept if the user wants to recalculate the model with changed parameters. If the user changes a geometric parameter, the file CAD can be reloaded; all model parameters are retained and the mesh is automatically rebuilt, whether generated by CENOS™ or controlled by the user.
