3DEXPERIENCE Launcher Certificate Expiring

Important Information for 3DEXPERIENCE On-Premises Customers

For all on-premises customers, the 3DEXPERIENCE Launcher includes an embedded certificate. This certificate is expiring on November 28, 2021 for the 3DEXPERIENCE Launcher version 21.16.778 (or lower versions). To avoid a potential interruption of service with the Platform, please read this article to assure continuation of service

NOTE: Customers using the 3DEXPERIENCE Cloud are NOT impacted by this certificate expiration issue.

What is the 3DEXPERIENCE Launcher?

The 3DEXPERIENCE Launcher is a utility that runs on the client machines, specifically client machines that use native applications, like CATIA or an integration, like to Microsoft Office or CATIA V5 or SOLIDWORKS that enables launching those applications directly from the web browser.

The 3DEXPERIENCE Launcher has an embedded certificate and that certificate is expiring November 28, 2021. After this date, the launcher will no longer function properly, in fact the call to launch the client software will fail due to an expired certificate.

To avoid an interruption in service the launcher can be upgraded but will need to be upgraded on every client machine in the deployment. The details of downloading and updating the launcher are detailed in the following FAQ QA00000065062.

For more information on updating the launcher software feel free to contact Adaptive Support.

Systems Engineering: An Implementation Journey White Paper

Dassault Systemes and SMS_Thinktank partnered up on a White Paper to provide a baseline when evaluating Model-Based Systems Engineering (MBSE): “Simplifying Model-Based Systems Engineering, An Implementation Journey“. 

The paper outlines what key strategies and considerations an organization should be aware of before embarking on an MBSE implementation.  Many characterize MBSE as a “system of systems thinking” due to the merging of engineering disciplines of mechanical, electrical, and software engineering.  It follows a model approach vs. a document-based approach.  An organization must take a step back and see the intersection and interaction of all the engineering dynamics when it comes to product development.

This paper suggests taking a look at three categories: 

  • Organization
  • Process
  • Technology

It is important to take a look at your engineering organization in an “as is” state to get an accurate baseline.  Analyze where there are misalignments and mismatches, fragmented processes and technology gaps.  It can be helpful to work with an external organization to help get an accurate, unbiased picture.

An excerpt from the paper notes:

MBSE moves an organization toward using a shared system model.With considerable planning, the perceived  journey may not be as traumatic as anticipated, especially for small to medium-sized businesses. The successful implementation of MBSE includes transformations in three key areas: organization, process and technology.

Organizational transformations start with gaining commitments from all levels of management and practitioners fused with the drive for success is critical to begin this evolution. Do not perceive this as a cultural change but as cultural growth. Collaboration is the lifeblood of implementation.

Process transformation starts with examining the area(s) to transform. Like fingerprints, no two MBSE implementations will be identical. The establishment and maintenance of a solid data and process management environment is crucial.

Executive sponsorship, corporate education and an outside point of view when needed all contribute to successful MBSE implementations. Governance involving executives, management and practitioners also accelerate and sustain progress. Establish milestones and reward accomplishments. Prioritize tasks and leverage high ROI short-term achievements, while ensuring proper linkage to the medium- and long-term goals.

Adaptive Adds CATIA Magic for Model-Based Systems Engineering

Adaptive is excited to offer you one of the strongest tools in the market that supports an organization that is looking to embrace Model-Based Systems Engineering or is fully engaged in an MBSE approach for innovation and product development.  We are now authorized resellers of CATIA Magic, part of the 3DEXPERIENCE platform.

What is Model-Based System Engineering?

Model-Based Systems Engineering (MBSE), as a cross-discipline collaborative activity, is a strong business enabler to address industry issues and to align organizations with current and future trends. 

Model-Based Systems Engineering is the formalized application of modeling to support system requirements, design, analysis, verification, and validation activities beginning in the conceptual design phase and continuing throughout development and later lifecycle phases.

MBSE is simply a set of visual representations based on a consistent and complete system model, which reflects multiple viewpoints of the system. These representations can be either static or dynamic (simulation), descriptive or predictive. It improves understanding, early in the development phase, system behavior as a functional digital twin of the product.

MBSE on the 3DEXPERIENCE platform

MBSE benefits include:

  • Better understanding of the mission, scenarios, and stakeholder needs.
  • Helps to define a consistent and complete system specification for the product designers through behavioral and structural analysis.
  • Specify with accuracy not only the static description of the interfaces, usually described in requirements but also the dynamic exchange of the interfaces that is inherent to complex systems.
  • Prevent costly late rework by understanding system behavior upfront, before prototypes are available.
  • Support cross-disciplinary collaboration around a system model based on dedicated views per engineering concern.

About CATIA Magic

In 2018, Dassault Systèmes completed the acquisition of No Magic (the leader in model-based systems engineering, and modeling solutions for software architecture and business processes) to strengthen its foothold in Systems Engineering and in order to facilitate new connected experiences.

EHD Bearing

The Simpack EHD module has been enhanced to include thermal balance and mass conserving effects in the fluid. This allows the EHD model to compute the temperature evolution over time in the fluid, allowing to observe the heating up of the bearing. The mass conserving algorithm will help the user to analyze cavitation effects and oil flows in more detail.

Additionally, the output of this element has been extended to provide out-of-the-box results at bearing half-width.

Dynamic Bushing

The dynamic bushing force element is used to model accurately the specific frequency behavior of engine and suspension bushing mounts. With recent versions of Simpack, there have been several enhancements brought to this element:

  • Optional direction coupling of the bushing stiffness

    It is now optionally possible to specify the coupling effect between different directions of the bushing. This can be used for example to better model cylindrical bushings with isotropic or orthotropic behavior.

  • Enhanced hysteresis shape definition

  • Dassault Systémes has introduced a new shape factor to refine the fitting of the shape of the hysteresis. This factor does not affect the overall amplitude of the hysteresis but gives the user control of the shape of the curve.

Electric Machine Interface

Since Simpack 2019x, Simpack supports the application of electromechanical forces with the Electric machine interface force element. This element can apply distributed forces on the stator and the rotor of the machine. It uses as an input a set of characteristic maps. A characteristic map is a map of lumped forces/torques or force densities as a function of the rotation of the rotor given at a specific speed/torque point of the e-drive machine.

The interface has been extended recently to support Reduced-Order Models that can be produced by CST Studio Suite. The added value of using a Reduced Order Model (ROM) for this application is that it is possible with a ROM to run different load cases such as torque run-up or speed run-up with one single element.

Simpack Roller Bearing

Several significant enhancements have been recently added to the Simpack Roller Bearing model:

  • It is now possible to apply a user-defined profile to the rollers

  • The lateral distribution of the loads on the roller can now be computed. This new feature vastly extends the functionality and applications of this modeling element. Including this bearing element in complete mechanical drives, models will provide improved results for misalignment calculations.

  • The contact force between the elements can now take into account optionally the damping effects due to lubrication.

Simpack Rail and Flextrack

Fast calculation of flexible track/structures

 

Dassault Systémes has introduced a new method for modeling flexible tracks called “linear Flextrack”. This new method considerably reduces the model build time and dramatically improves the solver performance, considerably reducing solve time. As an example, Flexible tracks simulations can now be run in a matter of few minutes rather than hours.

Improved Rail Contact Model for Supporting Standstill

The Simpack Rail contact model has been extended to support standstill conditions as an option in the rail/wheel pair element that allows for the stick/slip transition of the rail contact at very low velocity. It is now possible with this option to model new workflows :

  • Emergency braking simulation

  • Improved static test rig set-up and analyses

  • Modeling real-life velocity profile of light-rail vehicles including stop/start behavior between stations.

With the Simpack Belt module, it is now possible to plot belt transverse deflections and stick-slip contours on the belt shape and other quantities such as longitudinal or normal force distributions.

This enables analysts to gain more insight into the belt behavior for typical belt analysis scenarios, allowing them to identify critical regions at first glance.

Case Study: Ligier Automotive and 3DEXPERIENCE Get Up to Speed

Our team recently had the chance to talk with Chris Ruthstrom, the Chief Engineer of the U.S. branch of Ligier Automotive, a worldwide supplier of racing cars.  Chris lead a digital transformation project with Ligier and implemented 3DEXPERIENCE with full PLM capabilities from their CATIA v5 instance.  The goal was to enable internal cross-functional communication and streamline collaboration with external partners.

The French arm of Ligier has been using CATIA for decades, but when they acquired the North American operations in 2016/2017, there was no effort made to synchronize or connect their systems, because at the time, there wasn’t a significant need for data transfer. “You don’t know what you don’t know,” Ruthstrom says. “There’s a huge amount of data transfer now, and there’s a hardware and software limitation. We’re actively working on breaking down those barriers.” 

There’s no question in Ruthstrom’s mind that 3DEXPERIENCE has made his processes and work more efficient. “Having it in PLM. Knowing when I grab a part file I’m grabbing the latest and correct one. It’s very fast, very powerful, and I’m able to get a lot done very efficiently,” he says.

He’s eager to implement his plans for expanding use of the platform, which will ultimately be used on every single Ligier vehicle platform and development program. But he’s also being careful to be systematic and logical as he implements new processes, in order to reduce redundancies across the company.

The first steps will be to get purchasing and acquisitions departments using the software, to add manufacturing process documentation to the system, and to create a direct link from design to manufacturing using the platform and its cloud implementation to share data. Download the full case study
