Launching CATIA 3DEXPERIENCE on CLOUD in the Administrative mode

Posted on September 29, 2020September 13, 2024 by Swapnil Deshmukh

To set drafting standards and set user default catsettings for 3DEXPERIENCE CATIA we need to launch CATIA in Administration mode (Admin mode). It can also allow us to lock certain software settings. For 3DEXPERIENCE CLOUD this can be accomplished using the following steps.

Click on the 3DEXPERIENCE/ IfWe Compass.
Select the small black/ grey arrow just to the right of one of the 3D Modeling apps (for example, Assembly Design).
A menu opens showing the available tenants as well as the 3DEXPERIENCE level being used.
From the menu, select the “Create Desktop Shortcut” icon (grey/ white arrow just to the right of the 3DEXPERIENCE level name).

A Shortcut for the selected app is now placed on the Windows desktop.

Open the contextual menu (Right-mouse-click) on the shortcut and select Properties.

Copy the entire text string from the ‘Target’ field, located on the Shortcut tab of the Properties menu.

Create a new Text file on the Desktop and name it with the extension of .bat, instead of .txt. Paste the contents from Step 7 into the .bat file.
Launch the Desktop Shortcut (not the .bat file at this point).
When the login window is presented, cancel it by selecting on the X in the upper right corner of the window.
Go to the CATTemp directory (for example, C:\Users\username\AppData\Local\DassaultSystemes\CATTemp).
Open the latest Session Info File (for example, SessionInfoFile_username_d070_h13m21_p13584_0.txt) from the CATTemp directory. Then scroll to the bottom of the Session Info File. Here, you will find the list of Arguments used for launching the application.
Add any missing flags/ arguments shown in the Session Info file that were not included in the shortcut target from Step 8 into the batch file from Step 9.
Note that steps 7-14 are required, that is, creation of a batch file (.bat), because the Desktop shortcut ‘Target’ field only allows 259 characters due to a Microsoft Windows hard coded limit.
In the Batch file add “-admin”, but without the quotes, just after exe of “3DEXPERIENCE.exe”
(for example, “C:\Program Files\Dassault Systemes\B423\win_b64\code\bin\CATSTART.exe” -run “3DEXPERIENCE.exe -admin” -object “-Url=https://tenant_name-tenant_path:port/enovia -MyAppsURL=https://tenant_path:port/enovia/resources/AppsMngt -tenant=tenant_name)
Save the Batch file ensuring that it remains as a .bat and not a .txt file.
Open the 3DEXPERIENCE CATEnv.txt file.
Enter a directory path for the “CATCollectionStandard=” variable. (for example, CATCollectionStandard=C:\Users\user_name\Documents\ My3DEXP_CATCollectionStandardDirectory). Enter a directory path for the “CATReferenceSettingPath=” variable (for example, C:\Users\user_name\LockSettings).
Double-click the Batch (.bat) file created in Step 9.
Specify the your 3DEXPERIENCE login credentials.
To be able to modify & create drafting standards you need to log in as owner role.
This will launch the 3DEXPERIENCE CATIA in Admin mode with the ability to set activity of locks in Me>Preferences and Me>Standards for setting drafting standards as per the requirement.

Generative Design – A New Era in Product Design

Posted on July 30, 2020 by Kaladhar P

For decades, designers have been following traditional design methods that involve lengthy processes and several iterations. But today, the advancements in software have made design process simple and swift while minimizing the costs entailed. Hence, designers skill up on design best practices to reduce the repetitive design work with the help of design templates and easily implement key user-defined features adopting the right tools. This will provide them more time for innovation and new product design rather than repetitive work.

Generative Design is one such system that is transforming the way we design. CATIA software applications creates optimal designs from the set of system design requirements provided. With minimal efforts, engineers can create and simulate thousands of designs in a short span of time.

How to transform the current traditional design into a new generative design?

Simply input your design parameters such as materials, manufacturing methods, size, weight, strength, and cost constraints and receive numerous manufacture-ready designs promptly. Using AI-based algorithms, the Generative Design system outputs a myriad of design options that meet your project goals or specifications. From the multitude of options available, you can choose the one that best meets your requirement.

Why Choose Generative Design?

Generative Design system is an excellent approach that enables designers to explore an array of designs without altering the predetermined design specifications. The simulation is built into the design process, where the design undergoes hundreds of iterations before giving the output. With generative design, focus more on your vision and goals rather than doing manual design iterations. Just give your inputs, find unimaginable shapes that align with your design specifications like weight, stiffness, durability, cost, and material.

New light-weight design and assembly methodologies

Manufacturing engineers are leveraging the generative design to create accessories and tools that are lighter and stronger. They are using it to minimize part weight, optimize material usage, maximize strength, and minimize costs. The largest manufacturing companies like Airbus are utilizing generative design to redesign their interior parts with reduced weight which minimizes fuel consumption and allowing them to save big. Therefore, if you would like to optimize your material usage and reduce weight while maintaining strength and stability then adopt the generative design system to create lighter, stronger, and more cost-efficient outputs.

Check out the workflow of generative design by Dassault Systemes and how different variants are created after multiple processes.

National Institute of Aviation Research (NIAR) at Wichita State University (WSU) collaborated with Dassault Systemes to launch a 3DEXPERIENCE platform to familiarize students with emerging technologies such as Multi-Robotic Advanced Manufacturing (MRAM), additive manufacturing, and the development of new engineered materials for future aviation innovations. The WSU-NIAR designed an unmanned aerial system (UAS) or drone using the Dassault Systemes 3DEXPERIENCE platform. One of the major challenges while designing the product is the weight. The team practiced Generative Design Engineering (GDE) to optimize the UAS Gimbal assembly for the cameras and allows topology optimization and CAD reconstruction on a unified platform. With this, the team was able to reduce the vehicle weight, which added 15 to 30 min of flying per battery charge.

WSU-NIAR also leveraged additive manufacturing combined with GDE to optimize standard parts while reducing the overall part counts, avoiding material wastes, and lowering tooling costs compared to traditional milling methods

A Technology Perspective on Occupant Ergonomics In Automotive Industry

Posted on December 18, 2018September 13, 2024 by admin_eds

The Automotive Industry is witnessing a transformation globally as well as in India. New technologies and government regulations are driving this transformation. More so, the Indian customers and their expectations from an automobile is changing notwithstanding the onslaught of shared and hired mobility service providers. It is imperative that Indian Automotive Industry takes cognizant of this and many of them already are. The consumer seeks a delightful experience from driving an automotive – be it shared or hired. The mileage and quality aspects are taken for granted while making a buying decision today.
Ergonomics is one of the areas which can bring a lot of experiential delight as well as adherence to safety norms. As norms become stringent and consumer preferences change to more personalization and comfort, many Automotive companies and component manufacturers are beginning to ensure that the products they manufacture are suited for the Indian demography. It is also important that they have the necessary technology platforms to do this. This article sums up the importance of Ergonomics and how Automotive Manufacturers can leverage technology platforms to ensure its compliance not only for the Indian market but also for the global market.

What is Automotive Ergonomics and its importance to the Indian Automotive Industry?
Ergonomics is the science that applies theories, principles, data and methods to product design, with the goal to optimize user comfort, health and safety, as well as overall system performance. Automotive ergonomics is the study of how an automotive can be designed better for human use.
India is a strong and emerging market for automotive companies. It is also becoming a hub for global R&D as well as manufacturing. The automotive industry is very mature in terms of adoption of Digital Product Design and Validation. With this background, extending product design to Occupant Ergonomics is very easy with right technologies at your disposal.

Ergonomics Simulation – Doing it digitally

EDS Technologies in partnership with Human Solutions has offered technology platforms to many Indian Automotive companies for ergonomics simulation. Using 3D body scanners from Human Solutions, ARAI has created the first comprehensive database for the Indian population which can be utilized by Automotive companies.

RAMSIS is the de-facto standard worldwide in Automotive Industry in Occupant Ergonomics Simulation for interior vehicle design. RAMSIS was developed by Human Solutions and a consortium consisting of all German car manufacturers and two seat manufacturers in the 1980s. Today, more than 70% of the world’s car manufacturers use RAMSIS. Development of RAMSIS is still heavily supported by the German consortium and new developments and functions are in most cases based on input from automotive customers.

The use of RAMSIS in the design process increases the ergonomics quality of products and makes ergonomics an integral part of the design process. It allows manufacturers to put the end-user in the center of the development process and build the product that will offer a safe and comfortable environment to the targeted end-user population. From the earliest stage of the design process, until the final layout of the instrument panel, RAMSIS provides the methods, data and information to make well-founded, optimal design decisions from an ergonomic point of view.

Instant Ergonomics in practice with software:

Automotive companies have realized the following benefits from RAMSIS in terms of
ergonomics and efficiency:

Faster time-to-market thanks to savings on time-consuming trial runs with test persons
Reduction in development costs of more than 50%
Detailed Statistical Knowledge about body dimensions and about ingress and egress
Realistic Predictions about future space and operation conditions inside a vehicle
Compliance with standards and ensuring of ergonomic quality such as the best accessibility and usability of all controls
Faster, enhanced product maturity and cost savings through the avoidance of planning errors
Virtual, International test collective to represent human size differences
Comparison of various vehicle concepts with the same test collective
Simulation of driver’s posture and motion behavior based on modern research
Effective integration into your product development process
Competitive advantages thanks to high level of comfort and safety

Traditionally, automobiles manufacturers from Europe, North America, South Korea or Japan were sold as it is or homologated with very little change from ergonomics perspective. Indian based OEMs also were also more focused on mileage. India has a very different demography when compared to these countries. It is important that products are designed and manufactured for Indian demography when the indented users are Indians.

Realistic Simulation Supports Expansion of the London Underground

Posted on August 14, 2015September 13, 2024 by admin_eds

Dubbed “one of the most complex tunneling projects in the U.K.,” the Bond Street Station Upgrade (BSSU) project is being carried out to satisfy growing traffic demands within London’s busiest shopping district, the West End.

Upon its completion, Bond Street Station’s daily passenger numbers are expected to rise from 155,000 to 225,000.

A project this complex in nature has to consider the existing tunnel infrastructure, as well as the stress and strains imposed by the surrounding soil layers for the development of new tunnels.

Dr. Sauer and Partners was contracted to provide such tunneling expertise. The company took on responsibility for preliminary-to-detailed design and

Using FEA simulation, they were able to virtually test the ground through which the tunnels are being dug alongside the existing tunnel structures.

This realistic assessment enabled them to improve upon the preliminary design, as well as bring greater confidence to the overall approval process.

To learn more, read the case study, “Tunnel Vision” to see how realistic simulation plays an important role in tunnel excavation.

We also encourage you to download the whitepaper by Ali Nasekhian, Sr. Tunnel/Geotechnical engineer at Dr. Sauer and Partners, which highlights the merits and shortcomings of large 3D models in tunneling.
