.full.mat file

An OptiStruct ASCII format results file.

File Creation

This file is created when the OUTPUT,MATRIX,FULL,DENSE/SPARSE I/O Options Entry is used.

File Contents

Output
Description
Full Stiffness Matrix
Is output by default or if the DENSE option is selected. If SPARSE is selected, then the sparse matrix with all the zeros excluded, is printed in the <filename>.full.mat file.
Full Mass Matrix
Is output by default or if the DENSE option is selected, for dynamic analysis. If SPARSE is selected, then the sparse matrix with all the zeros excluded, is printed in the <filename>.full.mat file.
Full Heat Capacity Matrix
This matrix is output for Linear Transient Heat Transfer. It is output by default or if the DENSE option is selected. If SPARSE is selected, the sparse matrix with all the zeros excluded is printed in the <filename>.full.mat file.
Full Conductivity Matrix
This matrix is output for Linear Transient Heat Transfer. It is output by default or if the DENSE option is selected. If SPARSE is selected, the sparse matrix with all the zeros excluded is printed in the <filename>.full.mat file.
Full Convection Matrix
This matrix is output for Linear Transient Heat Transfer. It is output by default or if the DENSE option is selected. If SPARSE is selected, the sparse matrix with all the zeros excluded is printed in the <filename>.full.mat file.
Grid-to-DOF Mapping Matrix
The full Grid-to-DOF mapping matrices are printed in the <filename>.full.mat file. For Linear Transient Heat Transfer analysis, the full Grid-to-Heat DOF mapping matrix is also printed.

File Format

The .full.mat file has the following format (which is similar for all matrices above):
Name
Content
Matrix Name
Identifies the matrix name (STIFFNESS, MASS, DOFS, CONDUCTIVITY, CONVECTION, CAPACITY, or DOFSHT)
ID
Is always 0 for full matrix output (for the <filename>.full.mat file)
Number Type
Identifies whether the matrix elements are Integers (1), Real (2), or Complex (3) numbers
Matrix Type
Identifies the matrix type of Dense (1) or Sparse (3) matrix
Matrix Size (mxn)
Indicates the size of the matrix (m columns and n rows)
Precision Information
Fortran precision information
Matrix Data
Matrices are presented as a list of Columns with a range of row elements for each column ID.
