Finite Elements Analysis Introduction

What is Finite Elements Analysis? Designers create products that relate to operations conditions requirements (loads, strength, vibrations ) The FE Analysis enables designers and analysis specialists to virtually assess and optimize the product behavior and sizing.

Why use FEA? Assess and optimize the product behavior and sizing enables then to: Improve product performance and quality, Reduce development costs, Reduce subcontracting costs, Reduce the need for physical prototypes, Minimize design error, and then costly redesigns.

Who use FEA? Designer Usually has CAD software but rarely has access to advanced analysis tools. Engineering Analysis Specialist Performs more generalised analysis, and typically uses a geometry engine to develop the analysis model. Advanced Analysis Specialist Uses highly specific applications, some with no geometry engine.

Finite Elements Analysis V5 Solution overview

CATIA V5 FEA Solution CATIA V5 offers a suite of products enabling to perform easy and fast, stress, modal and dynamic analysis of any type of assembly The key highlights of the V5 FEA Solution : Accelerates Design - Analysis loops Easy to Understand and to Use Knowledge-Based Optimization Fosters Collaboration Scalable & Open Industry Proven Solution

Fast Design - Analysis Loops (1/3) The common CAD - FEA environment and the generative and associative specification driven capability permits a wider number of mechanical behavior and sizing assessments of parts and assemblies earlier in the product development process. On some components, it was possible to improve cycle time by 60%. Hans-Georg Schroeder Analysis Engineer at the Daimler-Benz Truck Division From preliminary design to preliminary analysis, CATIA's integration of Computer Aided Design (CAD) with Computer Aided Engineering (CAE) is a key success factor for reducing design cycle time Mr. Olesen, Project Engineer Per Udsen Company As analysis specifications are an extension of the part/assembly design specifications the impact of design changes can be rapidly reassessed with automatic updates.

Fast Design - Analysis Loops (2/3) Focus : V5 FEA is specs driven The definition of the Finite Elements Analysis is done through different attributes relative to the product operations conditions requirements. These attributes include : FE model : 1D/2D/3D mesh & properties, connections, Simulation definition (cases) : loads, constraints, Results management : images, sensors, These attributes drive (i.e. enables to generate) the FEA : the FEA is then specifications driven. This enables : the update mechanism, the specifications can be replayed to capture process through VB macros, the specifications can be automated

Fast Design - Analysis Loops (3/3) Focus : V5 FEA is associative The FEA specifications are fully associative with the design, meaning that when the design change the FEA is automatically updated according to the design modifications. The V5 infrastructure brings 3 levels of associativity, from geometry to lifecycle: On publication On mechanical feature On geometry Follows design semantic Follows design geometrical changes Enables users to update the FEA automatically (without redefine it) after a design change Ex: Pressure applied on a split feature Follows design life-cycle Ex: Replace component with same published features Enables users to re-apply automatically an existing FEA (mesh, loads, constraints, postpro ) on a new product version Enables users to update the FEA automatically (without redefine it) after a design change V5 associativity power

Easy to understand and to use The integrated and automatic approach for pre- and post-processing as well as for solving offers a very intuitive interface best suited to the needs of the designer, design engineer and analyst. Users handle mechanical features (loads, restrains, material, connections between parts ) instead of finite elements (nodes, elements). The FEA is transparent.

Knowledge-Based Optimization (1/2) The analysis suite of products takes advantage of the native CATIA knowledgebased architecture. You can achieve highly sophisticated design optimization by capturing and studying the knowledge associated to your part design and associated analysis. You can also reuse analysis features and apply knowledge based rules and checks to ensure compliance to company best practices.

Example Knowledge-Based Optimization (2/2) 1 Associative Analysis specifications 5 Design optimization using analysis results 2 Knowledge applied to Analysis Specifications 3 Generative Analysis PEO 4 Check of Analysis Results using knowledge Rules

Scalability (1/3) The CATIA V5 Analysis address the needs of: solutions Engineering Analysis Specialist Designers, Engineering analysis specialist, and Advanced analysis specialist, either on their own or through the extensive range of applications available through CATIA s analysis partner solutions, which are all based on the V5 architecture. Designers + CAE V5 Partners Advanced Analysis Specialist These partnerships extend the process coverage and address more specific needs such as multi-body dynamics, fatigue, acoustic, and thermal to name just a few.

An Industry Proven Solution The ease of use coupled with a common user interface and fast computation time provides a rapid return on investment. The analysis process is supported by a robust built-in finite element solver and mesh generators, balancing accuracy and speed. Additionally, users can review the characteristics of their design in a DMU environment getting a real idea of the mechanical behavior providing an opportunity to improve and optimize the design early in the development cycle. Very few Formula 1 teams can calculate and simulate mechanical component behavior. Our ability to do this gives our team a distinct competitive advantage in engine design and cycle times.
