Finite Element Method I FEM

Calculation and Simulation with SIMULIA Software around Abaqus Unified FEA

With the help of FEM software, you as a user can simulate the real behavior of components with geometrically complex shapes under a wide variety of conditions and thus make your development process much faster and more efficient.

What is the principle of the finite element method?

The component to be analyzed is divided into smaller, for example tetrahedral segments. So-called “finite elements”. Since the behavior of these partial elements can be calculated, the behavior of the entire component can also be approximated with the aid of numerical approximation methods. Even before a prototype is built, any number of tests can be carried out using such a virtual model. This significantly reduces the number of physical prototypes required.

In the automotive industry, for example, development teams are able to use a common model data structure and integrated solver technology to investigate complete vehicle loads, vibration dynamics, multi-body systems, impact/crash, nonlinear statics, heat coupling, and the coupling of acoustics and structural behavior. 

 

What makes us specialists in the field of FEM simulation?

When our company was founded in 1971, Wölfel was one of the pioneers in the finite element method in Germany. Today we are one of the leading engineering companies in Europe with over 800 projects in our fields of structural mechanics, dynamics and acoustics every year.

As a certified Dassault Systèmes sales, support and service partner, we also work with one of the leading developers in this field. Our portfolio ranges from FEM calculation with SIMULIA/Abaqus, topology optimization with SIMULIA/Tosca and parametric optimization with SIMULIA/Isight to lifetime calculation with SIMULIA/fe-safe. With these optimally coordinated simulation tools, users can realize routine tasks as well as complex development projects regardless of their industry.

SIMULIA/Abaqus Unified FEA

The world's leading software suite for modeling, solving and visualizing structural finite elements

In order to virtually depict individual design variants in the development process, several simulation tools from different providers are often used. However, working with heterogeneous simulation environments is often error-prone, labor-intensive and thus ultimately expensive, especially with regard to data transfer. SIMULIA provides a scalable range of coordinated analysis tools under the Abaqus/CAE user interface. Simulation data can be seamlessly exchanged, processes are optimized and consolidated.

The extremely powerful and reliable solvers Abaqus/Standard and Abaqus/Explicit make the software suite particularly suitable for simulating complex processes, which include:

 

  • Highly non-linear material behavior
  • Variable geometry with extremely large deformations
  • Contact and self-contact
  • Multi-physical phenomena (e.g. fluid-structure interactions)
  • Transient dynamic events (e.g. drop tests/crash)

The advantages of SIMULIA/Abaqus at a glance:

Fast evaluation of different variants

 

Lower costs through fewer and more targeted trials

 

Improved product quality

 

Comprehensive software package combined in one license
(SIMULIA/Abaqus + SIMULIA/Tosca, SIMULIA/Isight and SIMULIA/fe-safe)

Topology optimization with SIMULIA/Tosca

Efficient structure design in shortened development time

Product innovations should be light, safe, comfortable, efficient and durable. SIMULIA/Tosca Structure helps engineers to design individual components or entire assemblies that meet these and other requirements and make optimum use of the available design space. 

Topology, thickness, shape and bead optimization can minimize material usage and weight and maximize overall product performance. As the various design variants are created, tested and compared virtually, the development time is reduced and the new product can be launched on the market more quickly. 

SIMULIA/Tosca Structure works on the basis of FEA simulations. Due to the seamless integration of the design data, time-consuming parameterization is not necessary. The tool is also suitable for particularly demanding tasks with contact, pronounced material nonlinearities and large deformations. 

The advantages of SIMULIA/Tosca Structure at a glance:

Improved overall performance of your product

Developing more durable and lighter components and products

Optimization with regard to production boundary conditions

Discovering new design possibilities

Reduced number of product development cycles

Automation of Development Processes with SIMULIA/Isight

Parametric Optimization, DOE and Robust Design

Today's complex product and manufacturing development often requires interlinked simulation processes, where the parameters and results of one software package are needed as input for another package. Manual input costs a lot of time, is prone to errors and slows down the entire product development process.

In SIMULIA/Isight, the process flow with all applications is graphically represented in a virtual test plan. Individual simulation applications or self-developed scripts can be directly integrated into the workflow using the "drag and drop" principle. Isight then automates the data exchange between the interfaces and the execution of the applications. In just a few hours, a large number of variants can be tested. In addition SIMULIA/Isight evaluates result variables and identifies the optimal design parameters (parametric optimization). 

The advantages of SIMULIA/Isight at a glance:

Automated data exchange in an open system

Acceleration of iteration steps and shortening of the development process

Increased quality and reliability of your product

 

Lower development costs

SIMULIA/fe-safe

The world's leading software for lifetime analysis of FEM models

Components and products are to be made lighter and lighter by using less material, without sacrificing quality and resistance. Because fatigue fractures are expensive and can lead to accidents, but at least to costly product recalls and warranty claims.

Manual definition and analysis of stress points is time-consuming and often inaccurate. If you add material at supposed fracture points due to wrong assumptions, the product is heavier in the worst case, but no longer durable.

SIMULIA/fe-safe uses multiaxial, stress or strain-based fatigue methods to analyze the life of a product. The software makes it possible to determine the influence of load histories from the manufacturing process, operating load, high temperature and creep.

The calculation is based on the results of SIMULIA/Abaqus or other common FEM solutions such as ANSYS and NASTRAN. The results are quickly available regardless of the complexity of the analysis and are visualized, for example, in Abaqus/CAE. Plots with isolines show the expected lifetime. Points at which a crack is to be expected are marked. 

SIMULIA/fe-safe has an extensive material database and is particularly suitable for products and components made of metal and elastomers. Assemblies with different parts, surfaces and materials can be analyzed in a single run.

The advantages of SIMULIA/fe-safe at a glance:

Fatigue hotspots are identified

Material can be saved or added in the right places

Extends the life of critical components

Product recalls and warranty costs are reduced
