Faster CFD.

EXN/Aero uses next generation parallelization schemes that reduces simulation times by up to 20x. It is the only solver that is truly optimized for HPC hardware. For a limited number of engineers, we are offering the ability to trial this on our cloud server. All you need is your browser and a mesh.

Lightning Fast

Run a DES/LES in the same time as a traditional RANS. Run more simulations in parallel, and complete them faster. 



Use our HPC cloud server and activate supercomputing resources on the fly. 



Our platform features a meashing tool, solver, and post-processing tool. 


Simple Workflow

Our graphical interface has an easy to use workflow that can be learned quickly.  



The dynamic load balancing uses your resources intelligently, whether you use GPUs, CPUs, or both.


Cost Effective

We have an on-demand pricing model, meaning you pay-as-you-go.

Alarmingly, two-thirds of companies are currently predicting that they will require a 10x increase in modelling performance over the next five years. To keep up with performance increase expectations, CFD software users face two choices - to be reactive or proactive.

By being reactive, CFD simulation teams continue to grow their computing cluster, eventually running into limitations and restrictions such as power, space, additional users and license costs. Over recent years, a number of advances have been seen in the development of hardware, but CFD vendors have been less proactive when it has come to accelerator-supported HPC software packages. Their platforms only achieve marginal gains from using HPC technology, which means the benefit does not justify the additional HPC hardware cost. 

By being proactive, the industry embraces and invests in true HPC enabled software, ultimately limiting and even reducing the amount of hardware required, and providing a platform from which they can grow and evolve with future trends. While writing code for accelerators is not easy, this is what was required to arrive at a truly optimized solver for HPC hardware. Envenio built its EXN/Aero software package to deliver economical supercomputing for all sizes of CFD teams (freelancers to large corporate teams), allowing businesses to not just reduce hardware investment, but to be confident in their ability to increase performance, and ultimately remain in line or ahead of their competitors. 

Currently, the world of HPC is experiencing a transition into a new era – the many-core era. This era, like those that came before, is driven by cost, performance and accessibility, with the numerous cores producing more computational power.

Bigger, faster, and higher resolution CFD for less

The productivity expectations for engineers continues to soar, while CFD tools remain stagnant. EXN/Aero will get you to the next level of output.
