MBS Virtual Tech Days on Nov 16-18, 2021

Join us and Dassault Systémes for this three-day MBS Tech Day series on November 16–18, 2021, where a forum for engineers and experts come together to present their work, exchange ideas and experiences with other experts, and learn about the latest developments in Multibody System Simulation (MBS).

SIMULIA Simpack, used for the dynamic analysis of any mechanical or mechatronic system, enables engineers to generate and solve virtual 3D models in order to predict and visualize motion, coupling forces, and stresses. 

With many of the world’s largest markets implementing stricter standards and more difficult certification procedures, manufacturers need to overcome difficult challenges and still focus on the customer experience.

During the three-day event, with a technical-packed agenda, we will be focusing solely on Simpack multibody simulation experiences and developments. We provide you the chance to find out how SIMULA Simpack can help you meet your targets and design better products. 


  • Automotive topics on November 16, 2021
  • Rail Vehicles topics on November 17, 2021
  • General MBS topics on November 18, 2021

Register today

Sign up for individual days or the entire event (each day requires an individual registration). The MBS Tech Days are a virtual event — join the session benefitting you most.

Kinetic Vision Uses SIMULIA Cloud for Cross-Industry Innovation

When Kinetic Vision first opened its doors 30 years ago, the company stood out with a unique service: helping clients to virtually test products using modeling and simulation in an era when the technology was rarely seen outside the aeronautical and aerospace industries.

Founded by Rick Schweet as an analysis company, Kinetic Vision has since grown into an integrated technology company, expanding its focus beyond modeling and simulation to other
technologies like computed tomography scanning, visualization, machine learning and non-destructive testing. The company now consists of eight different groups focusing on these various technological services. “We are a services company. We help other people make their things better,” explains Shane Mooney, Group Manager of Kinetic Vision’s Modeling and Simulation Group. “We’re just a group of talented people with diverse backgrounds and diverse skillsets who are really interested in the creative problem-solving method.”

Kinetic Vision Case Study


Kinetic Vision Chooses SIMULIA Cloud

Adaptive introduced Kinetic Vision to the benefits of SIMULIA cloud and allowed the company to run some small pilots—with fantastic results, according to Topich. “Adaptive is a continued resource that we lean on regularly to bounce ideas off to figure out new ways to solve problems,” he says. “We have a great relationship with them, truly something we value.”

Adopting cloud services through the 3DEXPERIENCE platform was a “no-brainer” according to Mooney. The cloud allows Kinetic Vision to scale “infinitely and instantly” for any project needs. If a client asks for a project that requires hundreds of simulations, that request can be rapidly fulfilled with the 3DEXPERIENCE platform on the cloud solution.

How to setup SIMULIA Established Product License using Managed DSLS

What is Managed DSLS?

Managed DSLS is also known as Managed Licensing service.

The managed licensing service provides you with the ability to run certain levels of on-premises DSLS-enabled apps. Which means that DS now offers the possibility of a managed DSLS which serves as an alternative to a locally installed license server.

With Managed DSLS, you have the advantage that no physical machine is required to install the DS License Server. The license server is fully managed by Dassault Systèmes and located in Dassault Systemes Cloud Datacenter.

Ordering LKO for Managed DSLS license:

  1. OML (Online Licensing Service) Product: To ensure that only the licenses belonging to you are granted to the licensing client, licensing clients require authentication. The authentication file has a .LIC extension, and is generated using OML product feature.
  2. License token features required to run the analysis.

Below details should be required in the LKO request while ordering Managed DSLS license:

1. Product section:

2. License Information:

NOTE: Make sure to have same Online Instance for OML product and for the license tokens feature shown in “License Information”

To select the “ACTIVE” Online instance ID for Managed DSLS license type please contact:

  • PARATE Sneha (spe4)
  • RANJAN Anurag (evz)

NOTE: Here “ACTIVE” instances refers to the internal users who uses (QAL) instances for internal testing purpose.

You will then receive an e-mail from Dassault Systems containing:

  • an authentication file (.LIC file)
  • one administration URL for connecting directly to the Licensing Service Administration Web User Interface
  • three service connection hostnames for accessing the license server fail over:

where customerID is your customer identifier provided by Dassault Systèmes. It is Online Instance ID in this case.

How to configure Managed DSLS license for SIMULIA Established Products

  1. The authentication file must be deployed on all your licensing client machines in the following default location:
  • C:\ProgramData\DassaultSystemes\Licenses (Windows)
  • /var/DassaultSystemes/Licenses (Linux)


You can also set the environment variable DSLS_AUTH_PATHNAME using a full pathname (UNC supported), if you decide to store the file in a different directory from the default one.

For Example: DSLS_AUTH_PATHNAME=G:\Shared\MyAuth.LIC

NOTE: If you do not set the DSLS_AUTH_PATHNAME variable, and there are several authentication files in the default location, only the most recent file (which supersedes the others) is taken into account.

  1. Retrieve the service connection host name’s from the e-mail you received and declare them in the DSLicSrv.txt file located in the above default directory given in step 2#. The port number should be 443 as follows:,,

For Example:,,

where r1132101281667 is the Online Instance ID and euw1-23swi10401 is the internal switch POD name for internal user.

  1. Check your network configuration (firewalls and proxies) to allow https access to the three hostnames on port 443.

Licensing Service Administration Web User Interface details:

After successful configuration of Managed DSLS license, you can logon to the URL with the below address:



  • Connection mode: Restricted access
  • Provide the Authentication file
  • Password: Your windows DS password. (It will ask to change password on logging first time)
  • Change the Password for Restricted access as “DS

Managed DSLS Eligibility

A Managed DSLS Eligibility Checker is available on in order to quickly access whether the customer is eligible to use the service.

On Demand Webinar: Battery Module and Pack Engineering

Learn how modeling and simulation helps evaluate and meet multi-objective requirements.

The correct battery pack design is critical to offer the range, cost, safety, durability, and driving experience customers demand. Integrating this technology into vehicles remains a challenge since the trade-offs between weight, cost and battery performance are so high. Balancing these aspects is key for both new market entrants and existing OEMs. In addition, the lack of physical testing facilities and the length of time testing can take only add to the challenges.

Register to watch this webinar on demand to learn how state-of-the-art modeling and simulation applications enable design and engineering teams to collaborate on the evaluation and improvement of multi-objective battery performance targets.

On Demand: Accelerate Electric Drive Engineering

Learn how multi-disciplinary workflows are used to model and simulate e-Drive systems and performance.

An electric drive is the heart of an electric vehicle. Its performance is measured by many attributes, with key factors being durability, efficiency, harshness, cost and weight.

Achieving the targets for these characteristics requires solving highly non-linear, multi-variable problems involving structural, thermal, electrical, and magnetic physics domains.

Since these design objectives are interdependent, they need to be evaluated on the complete system, including the electric machine and the gearbox.

Watch this on demand webinar to learn how Dassault Systèmes electric drive engineering solution provides multi-disciplinary workflows to design and simulate the complete performance of an e-Drive in a short amount of time.
