CFD Simulation Software

World Class CFD Simulation Software from a globally trusted, expert industry partner

For over 30 years, ICON CFD simulation software has delivered more accuracy, more speed, more flexibility, greater capacity. It provides global industry customers, especially Fortune 500 companies, the opportunity to save millions in annual CFD software license fees. There’s no requirement to be locked in to an expensive, long-term contract either with lost time in months of complex contractual negotiations with sales people focussed on maximising their commission.

The big difference is that we are engineers first, not just expert coders with exceptional software. As such, the conversation is about solving your problems and helping you achieve your desired improvements and development objectives, NOT about selling you a product – a refreshing change perhaps, compared to some.

In summary, key features of iconCFD® simulation software are:

  1. A fully supported industry product from the longest and largest provider of industry robust open source based CFD software
  2. Unlimited scalability on each HPC system while maintaining comparable levels of accuracy and ease-of-use
  3. Single, global development and delivery team experts in Meshing, Solving, Front-end, AI, etc
  4. The same CFD simulation software the ICON engineering team use for their own consulting projects
  5. Only a few hours of user training required

The table below sets out the software modules available and an example of their application in the automotive sector:

Our on-premise and cloud-based CFD products and expert services deliver significant operational, commercial and competitive benefits for clients:
