Subprogram

1. MSCS(MSCS.C)

The Multi-Scale Computational Software for the Macroscopic Parameters and the Structural Analysis of the Composite Materials.

MSCS.c is the main program, and contains three modules: Ran-Grain Auto-FEMeshes and MSC-Macro-Para shown as follow. The final results are stored in files: u0material.dat and umaterial.dat.

File name	Description
u0material.dat	Contains the homogenization parameters of each specimen.
umaterial.dat	Contains the final homogenization parameters.

2. Ran-Grain(Ran-Grain.C)

The Computer Simulation of Random Distribution Model of Grains/Foams/Cavities.

There are two input files (ellipsedomain.dat and ellipsetotal.dat) and five output files (file5.m file6.m file6.dat equation6.dat totalpoufen.dat). The description of these files can be found in the following table.

File name	Description
ellipsedomain.dat	Determine the geometric parameters of the cell and the elliptic spheres.
ellipsetotal.dat	Determine the total number of the elliptic spheres and the mesh parameters.
file5.m	Matlab file. To plot the elliptic spheres generated by this program in Matlib.
file6.m	Matlab file. To plot the boundary points of the elliptic spheres in Matlib.
file6.dat	The data of the boundary points which will used by Auto-FEMeshes.
equation6.dat	The 10 parameters of the general equation of each elliptic sphere.
totalpoufen.dat	The contral parameters of Auto-FEMeshes.

3. Auto-FEMeshes(Auto-FEMeshes.C)

Auto-Generating Finite Element Meshes for a Grain Distributin Model.

The input parameters that this subprogram needs are stored in totalpoufen.dat file6.dat and equations6.dat which are the output files of Ran-Grain.

The following table shows the content of the output files.

File name	Content
node.dat	Contains the locational parameters of the nodes.
element.dat	Contains the four node numbers and material number of every element.
boundarypoint.dat	Contains the parameters of boundary points.
homototal.dat	The information needed by next computation(MSC-Macro-Para).

4. MSC-Macro-Para(MSC-Macro-Para.C)

Multi-Scale Computation for Macroscropic Parameters Based on Random Distribution.

The output files (homototal.dat node.dat element.dat boundarypoint.dat) of Auto-FEMeshes are the input files of MSC-Macro-Para. Besides these, another two files named material.dat and youxyuandomain.dat are needed, where material.dat contains the imformation of materials and youxyuandomain.dat contains the geometric parameters of the cell.

Some FORTRAN files are needed too. They are shown as follow.

File name	content
