Week - 5 - 2D meshing for Plastic components

• Objective

CAE significance has gained ground in the recent years through the introduction of the No Prototype car concept. Modern models consist of numerous components with different design variants and CAE needs to face the challenge of minimizing turnaround times and providing error-free processes that will allow engineers to go through simulation results in an effortless and efficient way. To address these needs, an automated process was built-up by BETA CAE Systems

ABSTRACT

The new approach resulted to a remarkable reduction of time, an augmentation in modelling quality, a more supervisory presentation of the results and a process less prone to human errors. Current functionality is planned to expand

Challenges of the Project

During the design and realization of the project some challenges arose concerning the input of the data for the process, the evaluation of the resul

Different areas of interest are applicable for each component. The specifications for the post treatment of each area of interest are strict and involve the definition of the elements belonging to each unit of the area (one spot face for the spots area of interest, one mig edge for mig edges area of interest, etc) through geometrical criteria, the extraction of the failed elements according to specific threshold value and their further individual post-procedure related to each component needs

An overview presentation of the model is created to check the total numbers, total length and positions of each connection per type or per connectivity. Further model checks include the displayOne of the two major functions of the process is the check of the model set-up for the simulation analysis. General information about the model is presented like the total number of the various elements types (sets and other entities), the parts and materials information while their location is displayed on the model

Results Query

Furthermore, in certain cases, interdependency among two or more results or between a result and model data is demonstrated in calculations, as in the slide below, where absolute torque values of spots are assigned to the connected parts and grouped according to the thickness.
