Introduction

In the realm of solid mechanics and structural mechanics, stress and strain analysis play a crucial role in understanding the behavior of materials under various loadings. MFree2D is an adaptive stress analysis software package that leverages meshfree technology to provide accurate and efficient solutions for 2D stress and strain analysis. Developed by Prof. G. R. Liu and his co-workers, MFree2D is designed to handle static and/or dynamic loadings with heat transfer processes, making it an indispensable tool for researchers and engineers in the field.

Overview of MFree2D

MFree2D is a comprehensive software package that consists of three major processors: MFreePre, MFreeApp, and MFreePost. Each processor plays a vital role in the analysis process, ensuring that the results are accurate and reliable.

MFreePre: Preprocessing

MFreePre is the preprocessor of the MFree2D software package. Its primary function is to formulate the input required by MFreeApp, the computational processor. The user-friendly graphical-user-interface (GUI) of MFreePre allows users to easily define the problem domain, specify the loadings, and select the desired analysis options.

MFreeApp: Computational Processor

MFreeApp is the computational processor of the MFree2D software package. It performs the actual computations and yields the results, which are then fed to MFreePost for post-processing. MFreeApp utilizes adaptive refinement techniques to ensure that the results are of a desired accuracy. This feature is particularly useful for complex problems where the solution requires a high degree of accuracy.

MFreePost: Postprocessing

MFreePost is the postprocessor of the MFree2D software package. Its primary function is to process the results obtained from MFreeApp and present them in a user-friendly format. MFreePost allows users to visualize the results, extract specific data, and perform further analysis.

Key Features of MFree2D

MFree2D offers several key features that make it an attractive choice for researchers and engineers in the field of solid mechanics and structural mechanics.

Automatic Discretization

MFree2D uses scattered nodes to discretize the problem domain, eliminating the need for manual mesh generation. This feature saves time and reduces the risk of human error.

Adaptive Refinement Techniques

MFree2D implements adaptive refinement techniques to ensure that the results are of a desired accuracy. This feature is particularly useful for complex problems where the solution requires a high degree of accuracy.

User-Friendly GUI

MFree2D features a user-friendly graphical-user-interface (GUI) that allows users to easily define the problem domain, specify the loadings, and select the desired analysis options.
