Now a part of the SIMULIA brand of products from Dassault Systèmes, CST Studio Suite is a high-performance software package for electromagnetic analysis of electronic systems and devices.  By combining the industries largest breadth of technology with a user interface that is second to none, CST Studio Suite delivers to users the most efficient returns.

Leveraging electromagnetic field solvers early in the product development process provides insights and answers so informed decisions can be made to yield the optimal product.  Drastic reductions in product development cost and risk, thru minimized prototyping, testing, and compliance failures, easily justifies the software investment and drives a positive ROI.  This result is unquestioned and exemplified by the heavy use at leading technology companies across the globe in areas of consumer, industrial, automotive, and mil-aero electronics to address various challenges, from performance of individual components like antennas and filters, to co-existence in complete systems like tablets and electric vehicles.


The success of CST Studio Suite is supported by three foundational pillars: technology, usability, and integration. 

Today, a versatile range of technology is paramount to success, and technology has been at the core of CST Studio Suite since inception.  To keep pace with the rapidly increasing demand to analyze more complex systems in less time, this technology, from user interface to postprocessing, must work in concert.  With technology tailored to electromagnetic analysis, CST Studio Suite is the only toolset to deliver in all phases.  Continue reading to see some examples.

The greatest technology in the world is useless if it cannot be used, and since inception CST Studio Suite has been widely recognized as the most user friendly.  With an interactive 3D modeler, schematic layout, synthesis modules, and postprocessing thru templates or free-form, unlocking the benefits of electromagnetic analysis is simplified to the max.  The strong emphasis on user interface, automation, and minimizing the engineering time spent driving the tool allows users to extract the most value from the software.  Read below for some of the key usability aspects.

  • Inherently parameteric user environment – if it can be a number, it can also be a parameter
  • Driven by scripts – the integrated scripting language allows for a highly automated workflow
  • The intuitive and easy to learn modeling engine is powerful enough to create the most complex geometries
  • Synthesis tools for antennas, filters, waveguide devices, and more
  • Drag and drop functionality
  • Automatic mesh generation and refinement
  • History list – modify and/or insert instructions in arbitrary locations
  • Integrated and automated postprocessing engine – optimize for any result
  • Powerful visualization and graphical rendering engine – even the most complex geometries and results are displayed and manipulated with ease
  • Component library to store and categorize results
  • System assembly workflow to easily combine various simulation models
