VisualFEA

VisualFEA is a finite element analysis program running on MS Windows and Mac OS X platforms. The program is being developed and distributed by Intuition Software, Inc. in South Korea, and is used chiefly for structural and geotechnical analysis. The strongest point of the program is its intuitive and user-friendly usage based on graphical pre- and postprocessing capabilities. VisualFEA has educational functions for teaching and learning structural mechanics and finite element analysis through graphical simulation. Thus, this program is widely used in college courses related to structural mechanics and finite element method.
Overview.
VisualFEA is a full-fledged finite element analysis program with many easy-to-use but powerful features, which can be classified largely into four parts: finite element processing, pre-processing, post-processing and educational simulation. All the functions are integrated into a single executable module, which is a characteristic of the program distinguished from other finite element analysis programs generally composed of multiple modules. The whole procedure from pre-processing to analysis, and to post-processing can be completed on the spot without launching one program after another, or without pipelining data from one program to another.
Processing.
VisualFEA can solve the following types of problems.
Pre-processing.
A finite element model in VisualFEA consists of various objects: curve, primitive surface, node, element and mesh. VisualFEA has its own CAD-like capabilities of creating graphical objects without aid of external programs. VisualFEA can create structured or unstructured meshes in two- or three-dimensional space using the following mesh generation schemes.
The program has the function to save the generated mesh data in text format for use by other application programs. Other pre-processing capabilities include the following items.
Post-processing.
VisualFEA has various functions of visualizing the numerical data generated by solving the analysis models. The most frequently used graphical representation of the data are the contour and vector images. There are many other forms of graphical representation available in VisualFEA.
Educational Simulation.
VisualFEA can be used as a tool for computer-aided education of structural mechanics and finite element method. The tools are operated with the user-created modeling data and their ensuing analysis results on the basis of finite element technology. They are devised to promote the understanding, and to stimulate the interest in the subjects by substantiating the conceptual principles and visually exhibiting the complex computational processes with the aid of interactive computer graphics. The topics covered by the educational functions are as follows.
VisualFEA/CBT.
VisualFEA/CBT is an educational version of the program published by John Wiley and Son's Inc. as a companion program to a textbook on finite element method. The program has the limitation of 3000 nodes that can be handled.
