EXN/AERO's Latest Features

Home » Blog » EXN/AERO's Latest Features

This article reviews the updated features list of Envenio's EXN/Aero. New features include porous media zones, passive scalar, and rotating frames of reference. Our recently launched alpha features include six degrees of freedom, NGON element support, solution monitoring, and free surface. Here at Envenio, we have been busy updating the features offered by our EXN/Aero software and wanted to share the latest developments. We want to share the latest improvements made to our software, all with the clear goal of improving the daily working lives of our users.

Breaking News...The Envenio Referral Program

Before we go any further, we want to tell you about our brand new referral program.The Envenio Referral Program has been introduced to celebrate and reward our much-valued customers, while introducing the platform to new engineers and building on what is already a successful and engaged community.

We are very excited to announce that you could be credited with $1,000 of on-demand EXN/Aero compute time should you refer someone who comes on as a customer! Get in touch to find out more about getting involved with the Envenio Referral Program.

Changing The Interface Of Simulation

We have made some significant interface updates, allowing you to report bugs more easily, and access the user-manual, release notes, and demo-cases to help you make full use of the software.



Introducing...Our User Manual

We are delighted to have launched our user-manual, and we are also planning to launch our theory manual soon. You can gain a sneak preview from the screenshot below;





Technology Core

EXN/Aero’s massive parallelization approach and domain load balancing undoubtedly distinguishes it from other CFD commercial software. The cost-effective approach aids us to enhance “Speed Ups”, a criteria that is widely recognized as a performance measure for parallelization. The solver will soon achieve a second level of Speed Up using unique technique for domain decomposition in both space and time.

Our unique cell & interface design subdivides simulation tasks into two classes of objects: cells and interfaces. The patented technology provides us with further flexibility and creativity in the parallelization scheme. Cell objects contain the CFD mesh and represent the bulk of the computational load while the interface objects are multifunctional data transformation utilities with numerous functions, including boundary condition input, cell-to-cell communication, reduction of output data, addition of source terms and interpretation of real-time sensor inputs.

General Improvements
