ENOVIA PLM Essentials, on the 3DEXPERIENCE platform, is a package of essential PLM capabilities for mid-sized manufacturers using CATIA V5, SOLIDWORKS, and/or 3rd-partry CAD systems. Capabilities include CAD and doc management, BOM management, Change Management and Project Management, plus social collaboration; these capabilities help increase revenues, improve product quality, shorten time to market, drive innovation, and achieve a competitive advantage.

Innovation is the only way to stay competitive and profitable, and even to survive. When non-productive tasks can be removed, engineering teams get more time back to focus on innovation and produce more alternatives to decide on the best solution.

We are hosting a live seminar with Dassault Systèmes on September 7th, 2017 at our Novi, MI headquarters. We’ll be covering all of the essentials topics discussed above and showing the value you can get by adopting the 3DEXPERIENCE platform.

Register to join us for a half day of education, networking, and lunch! If you want a closer look, stay after and chat one-on-one with our team. A full agenda is available to peruse on the registration page as well.

Many of our Abaqus customers don’t know that the Computational Fluid Dynamics approach (CFD) is not the only method of modeling fluids in Abaqus. There are many other possibilities and the right approach depends on the physics of the problem. This blog post discusses the multi physics methods of modeling fluids in Abaqus.

  • CFD method: This is the well-known and traditional method for fluids modeling. It’s based on Eulerian formulation, in which material flows through the mesh and can be accessed through the Abaqus/CFD solver. Application example: Flow through exhaust systems.
  • CEL method: This is a coupled Eulerian Lagrangian method primarily used in problems involving unbounded fluids where fluids free surface visualization is required. It’s also possible to simulate interaction between multiple materials, either fluids or solids. This method is accessible through Abaqus/explicit solver. Application example: Fluid motion in washing machine.
  • SPH method: This is a smooth particle hydrodynamics approach primarily used to model unbounded fluids that undergo severe deformation or disintegrate into individual particles. This method uses a Lagrangain approach in which material moves with the nodes or particles and can be accessed through the Abaqus/explicit solver. This method can be used for fluids as well as for solids. Application example: bird strike on an aero structure.

We can compare these three methods against multiple parameters such as materials, contact, computation speed, etc. to understand their applications and limitations:

  • Material considerations:

SPH method is most versatile in terms of material support. SPH supports fluids, isotropic solids as well as anisotropic solids.

CFD is the only technique that can model fluid turbulence

CFD is the only technique to model porous media

CFD and CEL allows material flow through the mesh: Eulerian

  • Contact considerations:

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.
