| Abstract: | An expert consultant and teaching aid has been developed to aid users of the MSC/NASTRAN (MacNeal-Schwendler Corp, Los Angeles, CA, USA) finite element code in the modeling process with two-dimensional elements. Written in LISP and LOOPS, an object-oriented programming language, the system, known as PLASHTRAN, allows engineers to work in a natural environment to obtain modeling recommendations. The program performs efficiently, especially when iterations in design require changes in the finite element model. The easily expandable modeling framework allows the knowledge base to incorporate new information. |
