Consultative Rule-Based Intelligent System for Finite Element Type Selection

Although the finite element analysis method is a well-known solution for complex engineering design problems, the right choice of the appropriate finite element type is often a problem even for experienced engineers. The paper presents a consultative rule-based intelligent system for finite element type selection. The aim of the system presented is to propose the appropriate type of the finite elements to be used for finite element analysis with freeware program Z88. The most appropriate type of the elements is proposed considering the problem description given by the user who needs to answer some questions stated by the system. Several examples will confirm that an expert system shell written in Prolog enables efficient use of the knowledge base and adequate communication between the system and the user. The system has the ability to explain the inference process. Thus, it can be used as a teaching tool for inexperienced users – the students. The results of the experimental use of the system are encouraging and can be used as guidelines for further developments and improvements of the system.
