Users of Dassault Systemes must have seen the following image multiple times in last few years. In this article, I am talking about what this image means from simulation perspective.

 

The image above is the brand logo of Dassault Systemes next generation innovation called 3D Experience platform. This image is called 3D Compass and its four quadrants symbolizes four major offerings  available in an integrated fashion with the platform. The north quadrant symbolizes collaboration, the east quadrant symbolizes 6W Tags, the west quadrant symbolizes designer applications and the south quadrant symbolizes our favorite simulation applications. The idea behind its introduction is very clear from simulation environment.

“BREAK THE SILOS”

The word silos may seem unpleasant to hear at times but that’s exactly how FEA or MBD simulation community has been since many years. These are small departments of very specialized people in large organizations that mostly work in isolation. The reason of working in isolation has been simple and justified till now. The complexity of products these specialists use has been an overwhelming task for other departments such as design, production, marketing, procurement, IT etc. that are a part of overall product lifecycle management. Moreover simulation forms a process of product lifecycle only when a new concept design is launched that has to be virtually tested either to save cost, reduce time or meet certain requirements imposed by regulatory boards such as NHTSA, FAA, FDA etc. This is not always the case.

The 3D Experience platform integrates and brings together all the departments involved in product lifecycle including simulation experts. The integration happens at base level by a data management and collaboration server called ENOVIA that allows users with different roles to create, modify, share, manage or propagate data from one person to other without using share drives, emails or any sort of data migration. In terms of T&M and A&D companies these roles might be product designers, design engineers, manufacturing engineers, FEA specialists, material experts, method developers etc. The platform offers roles for users. Each role is a collection of apps just like we see in our mobile phones. However, in case of 3D Experience platform, these roles are divided in four different categories based on four corners of the 3D Compass. These are 3D Modeling apps, Social and Collaborative apps, information intelligence apps and simulation apps. Few of these apps serve as pre-requisites to any user who wish to be a part of platform. But others such as simulation apps are assigned only to those users who wish to perform simulation.

 

With the 3D Experience platform, a simulation expert works on the same data that is created by a designer to perform simulation without any manual data transfer. No more specialized product formats such as Abaqus CAE, Tosca, fe-safe that have their own file architecture not compatible with designer products such as CATIA, Creo, Solidworks etc. Once the simulation is complete, results are stored in the same database that can be instantly viewed by engineering managers, product designers, R&D head or any user who is not actively using simulation. So no more specialized output file formats such as odb, conf, ldf, stlx etc. A simulation role armored with simulation apps allows a specialist to get into the platform, access the data created by designer, create simulation model in same environment, perform the analysis on user machine or on cluster and publish and share the results. Simple it is! Once the silos are broken, there is yet another aspect of 3D Experience platform that makes it unique in the way it works.

“ELIMINATE FILE BASED FOLDERS FROM THE SYSTEM”

Everything created or imported in the platform is saved within the ENOVIA collaboration server. The data can reside either on-premise or on-cloud based on chosen architecture. The user can search or access the data using advanced 6W Tags search criteria based on questions such as who, what, when, where, which etc. In case of cloud based architecture, this data can be assessed and modified from anywhere using devices such as smart phones or ipads. Can your smart phone read Abaqus odb files! The answer is perhaps no but yet it is possible to access Abaqus output data on smart phones using 3D experience platform.

Today’s topic will focus a little on the licensing side of CATIA – namely CAT3DX and the theory of what it is here for.

Several years ago, Dassault changed the way they were packaging CATIA V5 by introducing PLM Express as a way to buy it; my colleague Jason Johnson explained this in a previous post. As he had mentioned, this was referred to as CATIA TEAM PLM and was really designed to allow for connecting current CATIA V5 users of their new PLM offering, which was ENOVIA SmarTeam.  He also wrote briefly about the configurations and trigrams that make up the software.  The easiest way to think about a trigram per se is to know that a group of trigrams make up a configuration, and trigrams by themselves give you access to particular workbenches – or in some cases only add toolbars to existing workbenches.

Why does this matter? Because there is a new sheriff in town called 3DEXPERIENCE. Much more than a PLM system, the 3DEXPERIENCE platform suite of tools will assist the user in management of their daily work, projects, processes, BOMs, documents, CAD, etc.  While an old CAC (CAT) license – which was the base configuration for PLM Express – would give you access to SmarTeam by bundling in TDM and TEM trigrams, the new CAT3Dx will now give you all of that, as well as access to the ENOVIA 3DEXPERIENCE Platform, by giving you the PCS and CNV trigrams as well. These are the minimum trigrams needed to connect to the platform (the price for admission).

The Dassault idea is still the same – help CATIA v5 users move away from file-based, directory-based storage (which has always presented its own challenges) and help companies regain control of their data via the new platform. The only caveat to this is that you would install ENOVIA to manage your data, which is not as simple as throwing in a set of discs like SmarTeam was. ENOVIA requires the setting up of a database using SQL or Oracle, and then configuration of the various pieces (web server, authentication, java virtual machine, etc.).  Once this has been configured, the base PCS, CNV combination gives you the ability to vault your data and set up workspaces for where and how it will be stored, as well as do some level of change management on it. (set up Change Requests and Routes for how your data will be routed) to get it through its life cycle to release.

The ENOVIA applications that come with the PCS, CNV combination are Classify & Reuse, Collaboration & Approvals, Collaborative Lifecycle, Design IP Classification, Exchanges Management, My Collections, My Issues, My Route Tasks, and X-CAD Design. These are plenty enough to help your team begin to get to a single source of truth – meaning, never having to guess what state the latest data is in.

ENOVIA Apps

You also have access applications for business intelligence information. This includes access to the latest technology of Dashboards.  Dashboards are ways of viewing data configured to your liking.  Not at all unlike the old igoogle portal which allowed you to customize your view of news, etc. In 2012 Dassault acquired Netvibes.

Information Intelligence

In today’s engineering environment, there are a plethora of design tools available. One question I often hear is “Why CATIA?” It’s a question that seems simple enough, but the answer is much more complex. CATIA generally involved a greater initial investment, but in terms of overall design cost, you may be surprised to learn that a CATIA license can be a real bargain.

Ask: “What are we trying to accomplish?”

What type of design work are you doing? Do you require the ability to create complex surfaces? Are you going to create a small number of models and small assemblies or will there be a large number of models and large assemblies? Are you sharing the models with customers or vendors? Do you start every design from scratch or reuse as much data as possible?

The list of questions above is certainly not complete, but you can see by the number of questions already posited, the answer is multifaceted.

Complex Surfacing

Let’s look at the creation of complex surfaces. Many CAD systems can create surfaces of some level, but what if your company needs to create complex shapes? Look at how many CAD systems can create complex surfaces, and the list gets shorter – much shorter. Next, how many systems can modify complex surfaces? One example of this is the actual morphing of a complex surface. One might use this ability to compensate for springback in a metal stamping or counteract warpage in a plastic part. Now the list is much shorter. CATIA can easily handle these operations.

Large Assemblies

Next let’s look at large assemblies – something on the order of 500-1,000+ models. While virtually all systems can create assemblies, what happens when these assemblies get very large? Can the system handle them? How are you going to manage these assemblies? Is the system still able to operate or has its performance degraded to the point that it is virtually unusable? CATIA can handle very large assemblies, entire automobiles, aircraft, ships, etc. With CATIA V6 the management of these models is OOTB. Again the list is short at this point.

Data Reuse

Lastly, let’s look at data reuse. […]
