Realistic Simulation

Simulia is Dassault Systemès brand that focuses on Realistic Simulation. The renowned Abaqus Unified FEA is the flagship of this brand – with it’s strong nonlinear and contact capabilities. Today Simulia consist of a strong portfolio of products to aid simulation-based design. Complementing Abaqus directly are FE-Safe for fatigue and durability analyses, Tosca-Structure and Tosca-Fluid for topology optimization and Isight for process automation and design exploration. The Simulia brand is continuously expanding, which is why today we cover simulations from the molecular scale with Biovia up to the logical scale with Simpack. Through heavy investments in internal R&D,  new and exciting partnerships and acquisitions of bleeding edge solutions – Simulia  can now deliver the most comprehensive simulation portfolio in the world.

Abaqus Unified FEA

The Abaqus Unified FEA product suite offers powerful and complete solutions for both routine and sophisticated engineering problems covering a vast spectrum of industrial applications. In the automotive industry engineering groups are able to consider full vehicle loads, dynamic vibration, multibody systems, impact/crash, nonlinear static, thermal coupling, and acoustic-structural coupling using a common model data structure and integrated solver technology. Best-in-class companies are taking advantage of Abaqus Unified FEA to consolidate their processes and tools, reduce costs and inefficiencies, and gain a competitive advantage.

The Abaqus Unified FEA is a collection of different solver modules of complementary and integrated analysis tools where the three main modules are:


    a general-purpose finite element module. It can solve a wide range of problems involving static, dynamic, thermal, electrical and electromagnetic response of components. Abaqus/Standard solves a system of equations implicitly at each solution increment


    a special-purpose dynamic finite element formulation. It is suitable for modelling brief, transient dynamic events such as impact and blast problems, and is also very efficient for highly nonlinear problems involving changing contact conditions, such as forming simulations.


    a computational fluid dynamics solver. It can solve a broad class of incompressible flow problems including laminar and turbulent flow, thermal convective flow, and deforming mesh problems.

Abaqus/CAE incorporates the analysis modules into a Complete Abaqus Environment for modelling, managing and monitoring Abaqus analyses and visualizing results.

fe-safeis the technical leader in fatigue analysis software for Finite Element models and is capable of meeting its users’ most demanding applications. It directly interfaces to all leading FEA suites and is used by leading companies in the transport and mobility, aerospace and defense, general manufacturing, power generation, marine and offshore industries worldwide to determine fatigue life and optimize designs. fe-safe is renowned for its accuracy, speed and ease of use.

fe-safe has been developed continuously since the early 1990’s in collaboration with industry to ensure that that it continues to set the benchmark for fatigue analysis software. It was the first commercially available software to focus on modern multiaxial strain based fatigue methods and the first to incorporate capabilities for non-metallic materials. fe-safe analyses metals, elastomers, thermo-mechanical and creep fatigue and employs the Verity structural stress method or the fatigue analysis of welded joints – the only commercial software to incorporate this methodology.

With fe-safe as an integrated part of the design process, customers have the ability to:

  • Accurately identify fatigue hotspots
  • Optimize design to use less material
  • Reduce product recalls and warranty costs
  • Validate design and test programsimprove correlation between test and analysis within a single user interface
  • Reduce prototype test times.
  • Increase confidence that your product design pass their test schedules as “right first time”

Isight & the Simulia Execution Engine

In today’s complexproduct development and manufacturing environment, designers and engineers are using a wide range of software tools to design and simulate their products. Often, chained simulation process flows are required in which the parameters and results from one software package are needed as inputs to another package and the manual process of entering the required data can reduce efficiency, slow product development, and introduce errors in modeling and simulation assumptions. SIMULIA provides market-leading solutions that improve the process of leveraging the power of various software packages. Isight and the SIMULIA Execution Engine (formerly Fiper) are used to combine multiple cross-disciplinary models and applications together in a simulation process flow, automate their execution across distributed compute resources, explore the resulting design space, and identify the optimal deign parameters subject to required constraints.

Our proven simulation automation and optimization solutions enable engineering teams to:

  • Drastically reduce design cycle time through integrating workflow processes in an automated environment
  • Deliver more reliable, better-quality products through accelerated evaluation of design alternatives
  • Lower hardware investments through effective use of legacy systems and more efficient job distribution
  • Eliminate the bottlenecks of ineffective communication by enabling secure design collaboration among partners
