Exciting news – we have launched a new Blog Site with its own domain – plmtechtalk.com. Check out the new and improved site with fresh content.
The current global events is expected to have a significant impact on operating models and business dynamics. Organizations will have to adapt to the new normal and prime themselves for growth in a new environment.
Here are a few quotes from industry experts:
“The COVID-19 Pandemic is fast-tracking Digital Transformation in companies” – Forbes
“Global companies have to be predictive and proactive in their decision-making to preserve business continuity and build enterprise resilience” – Ernest Young
“Generating value while restarting your supply chain” – Bain & Company
“Its not business as usual, so don’t do business as usual” – Gains Group
This is specifically true for a company’s supply chains which are facing multiple challenges. So how does an organization respond to these challenges and reset a supply chain to make it robust and future proof?
It is clear that there will be two major trends for manufacturing companies when it comes to supply chains:
In addition to these trends, Enterprises are facing additional complexities:
Apart from the complex scenarios laid out above, supply chain management in the complex new world face multiple uncertainties:
So how does an organization start along the road of Supply Chain Diversification and create a network of suppliers that can thrive in the new normal?
The first step is a well orchestrated assessment that fully recognizes the in depth exposure a business has to its current supply chain:
Tata Technologies has devised a framework for an organization to reset its supply chain strategy – ReSeT.
OEM’s need to identify immediate system Restart challenges, devise action plans to Stabilize operations in the medium term and equip themselves to Thrive in the new normal by de-risking supply chains. Business as usual “won’t” be as usaul anymore. To thrive, organizations have to adapt to the new normal
So what are the actions required for the three horizons?
Tata Technologies brings deep expertise in engineering services and complete digital solutions to assist business navigate through the supply chain rationalize challenges
Tata Technologies has developed a holistic set of tools for supply chain diversification – Optimized Supply Chain and Risk Assessment
OSCAR consists of a combination of digital accelerators and industry expertise.

Dassault Systemes users are well familiar with 3DExperience rock N roll initiative that has been well perceived so far. The concept behind it is two fold: collaboration and integration. That means if all project stakeholders are using a single application, they can communicate with each other much more seamlessly than otherwise. The collaboration and integration include all aspects of data management spanning over design objects, simulation objects, PLM documents, project management, program management etc. This is a big transformation from DS offerings few years back that included disconnected point solutions such as CATIA V5 for design, Abaqus for simulation, Delmia for manufacturing, Smarteam for data management and others. If we look at simulation in specific, its worth mentioning that this transformation is not pertinent to Dassault Systemes but to simulation industrial landscape in general. Let’s see what others have been doing recently in simulation space:
SIEMENS: One of the big players in Simulation space is Siemens. In January 2007, Siemens officially announced the acquisition of Unigraphics Systems referred to as UGS. Subsequently UGS FEMAP and NX Nastran offerings from its PLM wing became Siemens assets. Gradually and efficiently Siemens bifurcated its NX Nastran solver offerings: one as a stand alone solver with and without FEMAP and other as a collaborative solver embedded in NX and coupled with Teamcenter data management engine. It is called Simcenter 3D which is considered a competitor of 3DExperience platform simulation roles.
ANSYS: In terms of Revenue, ANSYS is the biggest player in simulation space. ANSYS has always been a simulation only company since its inception in 1971. Its traditional product has been ANSYS Classic that included a dedicated Pre-Processor coupled with FEA solvers for specialized analysts. ANSYS made its first move in designer space many years ago by introducing ANSYS workbench. It offers a much easier GUI based process automation compared to complex APDL language approach. In 2014 ANSYS acquired a 3D modeling application called SpaceClaim. This tool helps to idealize and defeature CAD geometry and make it more suitable for downstream simulation applications. In 2019 ANSYS acquired Granta Design, a material intelligence application having plethora of design and simulation material data. All these efforts have been geared to integrate design and simulation though ANSYS never had a robust SLM or PLM engine of its own other than Minerva.
AUTODESK: In December 2008, Autodesk acquired ALGOR, a small and standalone simulation company that offered a dedicated pre-processor and non-linear solver for simple to moderately complex FEA problems. In May 2014, Autodesk acquired yet another FEA solver called Nei Nastran well known in linear dynamics space. These two acquisitions made Autodesk well equipped with a linear and non linear FEA solvers. Subsequently Autodesk integrated these solvers with its Autodesk inventor CAD tools. These solvers are now offered as designer friendly CAD embedded finite element analysis software. This shows a dedicated effort from Autodesk towards design and simulation integration.

3DEXPERIENCE: A Virtual Journey
Analysts are analysts and they have an analytical mindset. So whenever a traditional Abaqus user is exposed to a radically different application such as 3D Experience platform, he looks at it with intricacy. The level of inquiry is high and meshing is always one concern that cannot be skipped. Quite often this discussion ends up in a comparison between 3DX meshing and Abaqus CAE or between 3DX meshing and third party meshing applications. This blog is around comparison between the Abaqus CAE and 3DX meshing capabilities. I have tried to make as many apples with apples comparison as possible by taking same part as reference in both the environments.
Take a look at the frame structure. It’s a thin solid part that has been meshed in Abaqus CAE as well as in 3DX. The frame has been partitioned at many sections to get maximum hexahedral elements. When this frame is taken in Abaqus CAE mesh module, it looks like this: The green region is structural mesh domain and yellow regions is sweep mesh domain. However, both of these approaches give a hexahedral mesh.
When the same part is taken in 3D Experience platform, there are bunch of meshing tools in the meshing app. However, the one most straightforward for use without as many partitions as used in CAE is the partition hex mesh approach. The technique shows the following color code.
Its worth mentioning here that in 3DX the yellow represents the sweep mesh region and orange represents the free mesh regions. This is different coding from CAE where orange represents region that cannot be meshed. The mesh looks as below with 75 percent hexahedral and 25 percent tetrahedral elements.
Conclusion: Using very similar meshing techniques of partition, we get different kinds of meshes in the two applications. At the same time, using a different design method with no partitions, it is possible to get all hexahedral elements in 3DX.
Its also worth to show here all the meshing methods in 3DX meshing app. While few of these are available in CAE as well, other such as partition hex mesh and hex dominant mesh do not. At the same time, CAE offers bottom’s up meshing method that does not exist in 3DX. So meshing comparison between 3DX and Abaqus CAE is indeed an apple with orange comparison.

One thing common between SIMULIA roles of 3DExperience platform and the standalone Abaqus products is that both require an Abaqus solver to perform computations. It further means that both solutions require Abaqus tokens to complete or speed up the computation part of the simulation. For standalone abaqus product, we know that the calculation is straight forward. Abaqus requires a minimum of five tokens to execute a single core non-linear job. Large models require more number of cores to solve in real time and more number of cores require more tokens as follows:
The computation capacity of 3D Experience platform, however, cannot be defined by a single equation. Unlike Abaqus solver, that is available as an integrated all-in-one license for all types of simulations such as standard, CFD, explicit etc., 3D Experience offerings are in form of roles. Each role is a sellable license that includes either some or all Abaqus solver capabilities. Offers are made further flexible by on premise vs. on cloud offerings. Let’s have a look at solver offerings in different configurations and roles.
Designer role vs. Analyst role
While most of design engineer roles have embedded Abaqus tokens, most of the analyst roles do not have any compute capacity at all. The number of tokens embedded in designer role depends on the level of simulation complexity a role can accommodate. For example
Structural designer role has 8 embedded tokens to accommodate up-to 4 cores job
Structural professional engineer role has 12 embedded tokens to accommodate up-to 8 cores job
It is possible to submit jobs on more number of cores than what embedded solver permits but in that situation external tokens need to be utilized and embedded solver takes no credit at all.
Tokens vs. Hours
In case of analyst roles such as stress analyst, fluid mechanics analyst etc., the role itself does not have any compute capacity which should be procured either in the form of tokens or credits. Tokens are renewable form of compute capacity which means they can be used over and over. 3D Experience uses tokens in a very similar fashion as does standalone Abaqus. The token consumption with respect to number of cores is the same for Abaqus as for 3D Experience platform. On the contrary compute hours are a non-renewable form of compute power. It means that hours, just like the talk time over phone, can be consumed only once.
Why compute hours at all!!!
In general compute hours is an expensive preposition for customer but there are exceptions. Compute hours are utilized to meet unexpected and rare increase in peak usage. This is somewhat more common in engineering consulting firms that can face high demand of simulation capacity due to influx of many short duration simulation projects at any time. To meet this sudden spike in demand, one-time compute hours bundle offering makes more sense than increase in perpetual tokens. Once peak demand is over and credits are consumed, simulation capacity is returned to normal levels.
On premise vs. on cloud
Design engineer as well as analyst roles are available in on premise as well as on cloud formats. There are three ways of utilizing cloud resources: store the models on cloud, stores the results on cloud and solve on cloud. The first two offerings require only cloud storage and are available at no additional charge with cloud based license. However, the third offering requires cloud compute resources that consumes compute hours in addition to cloud based license.
