INTRODUCTION

  FEMGV is an interactive graphical pre and post-processor for the Finite Element Method of analysis. FEMGV is the logical integration of the mesh generation program FEMGEN with the results assessment program FEMVIEW.. It may be interfaced to any finite element analysis program, and so it can provide users with a common pre and post-processing facility over the range of their finite element analysis requirements.

The use of any finite element analysis program comprises essentially three stages:

1.

preparation of the model data (pre-processing)

2.

analysis of the model

3.

assessment of the results (post-processing)

Whilst the development of better algorithms and advances in computing technology have enabled finite element techniques to be applied to increasingly more complex problems, the tasks of data preparation and of result assessment can be discouragingly time consuming and prone to error.

FEMGV addresses itself to the twofold task of generating the finite element model, and of enabling users to present the results of their analysis in an informative and illuminating way.

A variety of techniques for the generation of a model and the display of results are provided in order to meet the individual needs of different models; and where a colour terminal is available, FEMGV will use colour to add information and to improve the user's ability to make a rapid assessment of his model.

With a database specifically designed to give analysis program independence, and highly organised data structures designed to meet the tasks of mesh generation and results assessment, and to give a good interactive response; FEMGV can provide the finite element user with an extremely flexible and powerful graphics pre and post-processor.
