Kick off the new year by discovering some of our most popular Tech Talks from 2022 by discipline. And stay tuned for upcoming 2023 Tech Talks!


Python Scripting for Abaqus

Python is typically described as an interpreted high-level general-purpose programming language whose constructs as well as its object-oriented approach aim to help programmers write clear, logical code for small and large-scale projects. Abaqus is distributed with a Python API, providing a means in which to interface with and automate pre- and post processing tasks, activities, workflows – or more generically, 3rd party Python functionality.

Watch this Tech Talk to explore some Python essentials and first steps that could transform your Abaqus investment and user experience.


  • Receive an introduction to the Python API which supports and enhances the Abaqus/CAE offer and experience.
  • Obtain an understanding of underlying Python fundamentals.
  • Learn how to modularize and standardize your Python workflows and underlying investment.
  • Gain an appreciation for 3rd party module integration. 

Linear Dynamics with Abaqus

This Tech Talk will be of interest to anyone faced with the challenges of simulating structures subjected to dynamic loads. We introduce you to the most important linear dynamics capabilities in Abaqus/Standard.

Learn about the several methods in Abaqus/Standard for real natural mode extraction, including the AMS method which efficiently extracts large numbers of modes of large structures. Find out what damping definitions are possible and discover the sophisticated damping definitions within Abaqus/Standard that may be needed to make your linear dynamics simulations more realistic. 


  • Extracting natural modes,
  • Transient modal dynamics
  • Steady-state dynamics
  • Damping

Modeling Rubber and Viscoelasticity with Abaqus

Do you run structural simulations including parts made of rubber, elastomers or plastics? These simulations may require you to model the time-dependent mechanical response of materials. Abaqus includes the necessary material models and nonlinearities to do all of this and more. 

This Tech Talk gives you practical information on using material models for elastomers and plastics. We introduce topics related to configuring material models for structural simulation in Abaqus, including an overview of hyperelasticity, adding viscoelasticity, stability, and calibration of material models.


  • Material models for rubber applications
  • Calibrating material models for structural simulation
  • Tips and tricks for hyperelasticity and viscoelasticity in Abaqus

Human Models and Bioelectromagnetic Simulations

Understanding the interactions between the human body and electromagnetic fields is of essential interest in many areas of research and engineering as those may be directly related to potential health risks and hazards. Checking safety is even a legal requirement for many applications. This is especially challenging as the inside of the human body is typically inaccessible to measurements which makes simulation the only reliable way to analyze these effects. 

This Tech Talk demonstrates how the different dosimetry values are simulated by introducing the CST human model family and the whole CST BioExtension library and concludes with bio-electromagnetic simulation examples from various industries. 


  • Overview of the SIMULIA Human Model Creation project, including model features
  • Additional dedicated Voxel and CAD-based human models
  • Medical applications 
  • EM exposure analysis for certification

Parametric & Non Parametric Shape Optimization of Electromagnetic Components using SIMULIA CST Studio Suite and Tosca

Parametric Optimization of Electromagnetic Components is one of the “work horse” tools for electromagnetic engineers since more than 20 years. While modern manufacturing methods like 3D printing allow then production of designs with very complex surfaces, the traditional optimization techniques limits the numbers of used parameters to describe the geometry.

This Tech Talk demonstrates recent improvements in CST Studio Suite optimization techniques as well as how to link SIMULIA’s Tosca non-parametric-optimization suite with the CST Studio Suite . After a short introduction to the principles of the non-parametric-optimization, the entire workflow, starting with a parametric pre-optimization step followed by a non-parametric fine tuning in Tosca will be demonstrated in a live demo.


  • Improvements in CST Studio Suite Optimization
  • Non Parametric Shape Optimization

Passive Component Design for Satellite Applications

In this Tech Talk, we explore how components for space applications can be designed and analyzed with the SIMULIA electromagnetic simulation capabilities. Using SIMULIA CST Studio Suite and Antenna Magus, we design and analyze single antennas and antenna arrays. Typical design output such as return loss and far-field patterns can be easily calculated and optimized to meet the requirements. Moreover, components such as filters, diplexers, and multiplexers can be efficiently modeled and optimized using our filter synthesis tool FD3D and FEST3D, an efficient filter simulation tool. We also show how low- and high-frequency solvers can be efficiently coupled for modeling different components.

Simulation for Safe, Comfortable, and Energy-efficient HVAC Systems

Heating Ventilation and Air Conditioning (HVAC) systems have become an essential part of building equipment, ensuring superior Indoor Environmental Quality (IEQ), especially around Thermal Comfort and Interior Air Quality (IAQ). 

New simulation capabilities can provide insights into the performance of an HVAC, and help improve its integration in the building, before even breaking ground on construction. Designing an HVAC system involves balancing the performance of the components, with that of the system assembly, validating thermal, structural, or even acoustic targets. When looking at building integration, 1D HVAC system models and 3D building models need to be simulated in an integrated solution. This solution can include zonal 1D and detailed 3D representations of a building to investigate key performance indicators for energy consumption, thermal comfort and IAQ, and assess present and even future usage scenarios.


  • Design HVAC systems with reduced energy consumption, meeting new requirements on noise, or refrigerants usage
  • Improved building ventilation and energy efficiency through integration & customization
  • Multiple iterations with quick system model for HVAC right sizing in buildings

Building Digital Twins for a Faster, Cheaper and Optimal Vehicle Design

In this Tech Talk, we describe the simulation tools and workflows used for thermal design of vehicles, establish that these tools are accurate, and detail their implementation at the component and vehicle integration level. We also show that using these digital twin technologies leads to significant savings in both time and cost and is, therefore, a must-have capability.


  • Introduce workflows and tools used to build digital twins for thermal analysis and how this leads to savings in time and resources
  • Describe how complete and accurate these tools and their impact on design both at the component and vehicle integration level
  • Highlight use cases that show the tools are streamlined and automated that enables non-specialists to implement them 

SIMULIA XFlow: Fluids Simulation to Improve Lubrication Performance

In this Tech Talk we discuss the features and improvements of XFlow version 2022x which focused on two main topics to improve the user experience, extend simulation capabilities and increase performance:
1. Lubrication applications, reducing development times and costs by minimizing the number of physical tests. Providing quantitative predictions for results like wetted area and churning losses that can be very difficult or impossible to measure experimentally.
2. GPU, which we believe will be a before and after milestone for XFlow given the huge increase not only on performance but in terms of making HPC intense computations affordable to average users


  • New features and enhancements in XFlow 2022x
  • MODSIM: Unified modeling and simulation on a common data model within a single user experience on the 3DEXPERIENCE platform
  • GPU, making high-performance computing (HPC) computations affordable to average users
