SIMTEQ Newsletter November 2022

Introduction
2022 Lookback
New Product
The art of engineering
New releases

Our family has a ritual on New Year’s Eve every year to reflect on the past year and write down all the significant things that happened to us that year, as well as to read what we wrote the year before regarding what we looked forward to or expected for the following year. In general, as everyone contributes to the list, we have these “Oh yes!” moments and general disbelief that so many things happened in the space of only one year, coupled with how different the past year turned out from what we thought it would.

As I looked back over 2022 from a SIMTEQ perspective, apart from the events and major milestones in our company’s history, I couldn’t help but also think about world events which made the headlines or which had a significant impact on our lives in South Africa.

Covid was everywhere and then, forgotten. Russia started a war in Ukraine and suddenly, our friends in Europe also seem to understand what load shedding and food shortages mean.

Elon Musk bought Twitter, then didn’t, then did and the soccer world cup kicked off in Qatar under great controversy while soccer fans cheer and human atrocities are topics for another day.

Politically the world is in turmoil while technologically, it seems there is just no slowing down the progress being made, or limits to what can still be done.

This is the world we all play a part in building, or destructing.

Are we making the world a better place? Intuitively, you may say no, but look at these well-researched statics you’ll find HERE and these tangible numbers are stating yes!

Child mortality rates are arguably the best indicator there is to the real state of a nation. A parent will do anything to save a sick child and will protect their children to the best of their abilities. This indicator covers everything from general living conditions, nutrition, education, financial ability and available health services.

Our world is improving despite what the media wants you to believe, just look at the numbers and ask yourself what role you play in it.

I would like to wish you a merry Christmas and a blessed New Year and it is my sincere hope that you will rest this holiday season and travel safely regardless of where you will be.

Regards
Managing Director

2022 Timeline

Elements – New Hexagon Product

Elements is a multi-fidelity, multi-domain modelling and analysis tool. Well, that is what the website says! What Elements actually is, is so much more. It is a tool that uses a system-level design approach, together with a broad scope of built-in engineering libraries to give you the ability to quickly create mechanical, electrical, hydraulic, thermal, pneumatic, and magnetic models with ease through a simple to use drag-and-drop interface.

Elements is powered by Maplesoft, the world’s leading symbolic mathematics engine, which has proven itself over many years in academia, research and industry.
Beyond the ease of modelling, Elements has exceptional visualisation tools, allowing you to visualise results as 2D graphs or as 3D animations (where applicable), making it possible to better interpret the design and response of a system.

With Elements you can rapidly test concepts, evaluate variables and determine optimum system and component layouts before you move on to more detailed modelling and analysis with Adams or Apex. With the full support for Functional Mockup Units (FMU), Elements has powerful interoperability with Adams and Easy5 and all other simulation tools which are FMI compliant.

This FMU capability is where the power of Elements really shines, allowing you to easily integrate your system level models (Controllers, Hydraulics, Pneumatics, Drivetrains, Cable Systems etc) directly into your detailed Adams simulations, allowing each tool to focus on doing what it does best, in order to obtain fully coupled (Co-Simulation) results of the complete system.

It’s finally time to start ditching all those complicated Excel spreadsheets and start capturing your industry knowledge into an engineering tool that will not only integrate with all your other MSCOne simulation tools, but will give you insights into the performance of your systems which you never thought possible!

SpaceX Falcon Heavy

On 1 November 2022, the first commercial flight of the Falcon Heavy launch system took place. For some people, it is just a tool, a method to deliver a payload into earth’s orbit, but for the engineers and scientists involved (as well as any space enthusiast) it was a dramatic show, worthy of a best picture nomination.

The Falcon Heavy launch system is in essence a Falcon 9 launch system where the first stage has been tripled. That’s right, THREE Falcon 9 first stages can provide more than 22MN of thrust from their 27 Merlin rocket engines. This means that SpaceX can launch 63.8t into low earth orbit (more than double that of the Space Shuttle), 26.7t into geosynchronous transfer orbit, or as much as 16.8t to Mars (more than enough to get an elephant to the Martian zoo), on a single launch.

The best of all is that these rockets are reusable, with rockets returning to a landing platform to be used again. Thus far SpaceX has performed 190 launches with 152 rocket landings and 126 re-flights.

Perfect landing:

Worthwhile Mention: ARTEMIS I

On 16 November the first ARTEMIS mission launched from Kennedy Space Center’s Launch Complex 39B. This launch is the first step of the ARTEMIS missions, to return humans to and establish a long-term presence on the moon.

ARTEMIS I is essentially the shake-down mission, to ensure everything is working as expected before the first crewed flight with the ARTEMIS II mission.

Actran 2023

Actran 2023 is now available at the Software Download Center.

Hexagon is proud to announce the availability of Actran 2023 suite comprising of new acoustic, vibro-acoustic and aero-acoustic technologies which will provide acoustic and NVH engineers access to new tools, provide easier ways to create complex models, and provide new ways to evaluate noise, both objectively and subjectively.

Release Highlights

Key highlights of Actran 2023 include:

New workflow for performing TL-based SEA 

A new workflow has been introduced as part of the Actran Workflow Manager that enables engineers to build a Virtual SEA analysis based on transmission loss (TL), damping or absorption coefficient data. This new workflow extends the previously released wizard available in ActranVI. TL-based SEA provides a fast and efficient way to tackle airborne noise issues, build a system-level analysis and explore high-frequency behaviour.

With this new workflow, engineers will be able to:

  • Easily create a TL-based SEA model via a guided and visual approach
  • Iterate rapidly and evaluate multiple configurations in seconds. 
  • Build system-level models based on component data

Improved automatic subsystem generation in Virtual SEA

Subsystem generation is a fundamental part of building a Virtual SEA analysis and Actran 2023 bring several improvements to the automatic generation of subsystems. The new improvements can provide up to a 75%-time gain for the SEA database creation as well as allow for better control of the generated subsystems.

These improvements can help engineers:

  • Reduce drastically (up to 75%) the computation cost by specifying the number of frequencies for the energetic database creation
  • Control the patch grouping in subsystems by allowing the user to specify a coefficient that can provide a coarser or finer subsystem distribution
  • Have a new subsystem configuration in seconds, since changing this coefficient does not require recreating the database.

Automatic coupling for trimmed body analysis

Coupling surface creation for trimmed bodies has been a time-consuming process, especially when modelling a full vehicle. Automatic coupling surface creation is now available in Actran 2023, in which coupling surfaces are automatically created with the click of a button between the structure and cavity in a fluid/structure/trim model. 

This new approach will:

  • Drastically reduce (from days or hours to minutes) the modelling time for large fluid/structure/trim models
  • Prevent mistakes in the coupling definition by allowing for the visualisation and modification of the generated surfaces within ActranVI

Aeroacoustic surface: an easier way to model fan noise

Fan noise modelling has become much simpler and straightforward in Actran 2023. The user only needs to specify the rotation speed and Actran will create automatically at the solver stage the coupling line which is used to sample CFD data in static or rotating domain.

With this new approach:

  • The coupling line generation and modelling is significantly simplified with minimal user interaction
  • Users can still control the location of the surface by either specifying a reference surface or coupling line location
  • Visualisation of the final surface can be created in ActranVI to better position it for better data extraction

New sound quality metrics for psychoacoustic analysis

Sound quality metrics for performing subjective noise analyses (psychoacoustics) have been integrated within Actran in two ways: (1) Various such as loudness, sharpness, roughness, tonality or speech intelligibility have been introduced to the API of PLTViewer in order to study those indicators on existing result files. Besides that, a dedicated workflow including detailed analysis plots and figures has been introduced in the Actran Workflow Manager. Based on acoustic data provided in WAV or PLT format, the user can now study in more detail the different indicators listed previously.  

Many more new features

Besides these key features, a number of other new features, improvements and bug fixes are included in this version including:

  • many ergonomic improvements in ActranVI such as a new plotting options, an audio player, new meshing tools
  • a number of improvements for NVH, such as new quantities for MSC Nastran post-processing and material encryption
  • many more improvements in aeroacoustics, the Workflow Manager and Virtual SEA.
