The finite element method is, alongside with CAD, one of the most

efficient tools for optimizing the quality of engineering tasks (Klein

2010). Furthermore, the currently available FE software is getting more

and more user friendly. However, especially less experienced users -

such as designers - perform more and more FE simulations but do not

have the knowledge of experienced computation engineers. Often these

users do not have a complete overview of the performance of currently

used simulation and calculation tools for securing product and also

manufacturing process characteristics. However it is highly essential to

optimize the quality and minimize the costs of a technical design as

early as possible during the product development process. Therefore,

these users need to be assisted when performing simulation tasks. This

can be achieved by an integrated plausibility check in the postprocessing

of the FE software. When an existing FE result data set is

checked for plausibility further steps towards a better assistance for part

time users can be taken. Such as an error assistant for implausible

results or a context-sensitive result visualization to help the user to

understand the simulated results.

The presented approach in this paper is part of the Bavarian Research

Cooperation FORPRO² for efficient product and process development

by knowledge based simulation. The aim of the Research Cooperation

is to increase efficiency of virtual product and process development

through the creation of an expert knowledge based simulation

framework for property optimization and quality improvement of new

products. The expected result is to provide the necessary situational

simulation knowledge as a function of decisive factors such as the

phase in the development process, the manufacturing processes

employed, and the company's individual circumstances. Within the

Research Cooperation an FEA-assistance system with an integrated

plausibility check is developed. In this paper an approach for plausibility

checks applicable for different standard components with mathematical

meta-models is presented. At first the terms plausibility, verification and

validation are distinguished. Then different meta-models and their

requirements and possibilities for evaluating the quality are shown. The

paper closes with an exemplary application – a piston pin of a combustion engine, for which a plausibility check with different mathematical meta-models is demonstrated.
