Learning with SIMULIA Users

21-06-2024 | Posted by Rafa Llorens

On June 12th, we held the SIMULIA users meeting. It has been almost 30 years since we started organising these events, where users can share their experiences and questions about simulation and the different products they use.

This year, Delphine Genouvrier from Dassault kicked off the event by explaining how AI (Artificial Intelligence), MODSIM (integrated design and simulation), and multiphysics will be trends in the coming years, and how SIMULIA will improve functionality, products, and infrastructure for any company in the industrial sector.

AIRBUS Defence and Space is one of the companies that have regularly participated as speakers at this event for many years. They always offer an innovative perspective on using Dassault’s tools. On this occasion, Miguel Ángel Alen and Rubén Casado presented, among other things, the case of dynamic analyses for multiple satellite separation: “The market was moving towards satellite constellations, and the biggest problem was the point-to-point separation systems, which are very complicated. Our goal was to cut costs, development time, and qualification. We achieved this by performing finite element simulations using Abaqus“.

MODSIM powered by AI is one of the trends that will shape design based on physics. Sebastian Zaje from Dassault Systèmes spoke in his presentation about how MODSIM technology, enhanced by artificial intelligence, helps reduce product development times, create more attractive products, and improve efficiency to work more effectively.

Sasa Dragas from SENER AEROESPACIAL explained several practical cases related to ATC antennas, GNSS, and high-power passive combiner devices. In the first one he stated, “We always seek simple solutions to complex problems. In this case, we had to switch from linear to circular polarisation without disconnecting the amplifier and with little time for mechanical changes.”

Subsequently, two of our SIMULIA experts at Principia, Javier Reboul and Javier Rodríguez, provided a brief overview of all the new features of the 2024 version for electromagnetic and structural simulation, respectively. Among the new features for fluid simulation, Santiago Garcia O’Regan from Dassault Systèmes pointed out that the 3DEXPERIENCE platform now includes the ability to simulate rotating meshes, as well as a substantial improvement in usability.

To close the morning session, Jérôme Noailly from UPF presented an interesting lecture on the role of simulation in studying non-communicable diseases and disorders, particularly focusing on the effect on tissues and organs that bear mechanical loads, such as the spine. Numerical models and simulations are increasingly valuable for identifying pathophysiological mechanisms and stratifying risk factors.


In the afternoon, the sessions were divided into two areas of knowledge. On one side were the sessions on structural simulation and optimisation, starting with a presentation by Margarita Riera from Dassault Systèmes, who shared with all SIMULIA users present how digital twin models streamline design phases by integrating structural modelling and simulation, significantly reducing potential errors. She illustrated this with the case of a submarine’s structural integrity.

She was followed by Sergio Sábada from IDOM, who discussed the need to build much more compact fusion reactors to reduce construction costs. For this purpose, they have developed a parametric tool in Abaqus/Python that allows the evaluation of a specific breeder blanket technology across the entire range of possible reactor designs.

José Manuel Bayo from CT Ingenieros presented the HALO Space project, which aims to commercialise tourist flights to the stratosphere. This involves, among other things, conducting implicit nonlinear analyses for more precise sizing to reduce the weight of this structure.

Lastly, Fernando Naya from Universidad Carlos III de Madrid explained the finite element model they have developed in Abaqus/Explicit to study the behaviour of a fibre-reinforced polymer based on its microstructure.

Meanwhile, those interested in electromagnetic, multiphysics, and optimisation simulations could discover the work presented by Jone Etxebarria from CIEMAT. She explained the use of CST in her research on hadron therapy or ion therapy and its advantages over traditional radiotherapy. Her work involves designing the part responsible for electron generation, which will then generate carbon ions for subsequent acceleration.

Joseba Bastarrarena from SUPRASYS explained how CST played a fundamental role in designing a SEPTUM to divert a portion of the deuteron beam. Ricardo Hernández from Jorcar Titanium, speaking remotely thanks to streaming capabilities, discussed an application of multiphysics simulation with SIMULIA products to address the design and manufacture of Ti frames using Abaqus. To conclude this session, Nicolás Escribano from Instituto Tecnológico de Aragón presented the multi-objective optimisation of a hyperelastic separator for the automotive sector, enabling the transmission of axial force between two aligned shafts.

To end the day, Miguel Herráez from Escuela TecnoDigital presented a numerical simulation strategy to predict the mechanical failure of structures made from recycled unidirectional “prepreg” sheets. This methodology has great potential to guide the design development of large components and structures manufactured with COSB.

Once again, we found ourselves surrounded by great professionals who go above and beyond to find solutions to engineering problems, transforming the world into a more efficient, sustainable, and ultimately better place through their pursuit of excellence and determination to do things differently. We extend our sincere gratitude for sharing all this knowledge and being an essential part of this meeting.
