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.
Grid-to-DOF Mapping Matrix
The full Grid-to-DOF mapping matrices are printed in the
<filename>.full.mat file.
File Format
The .full.mat file has the following format:
Name
Content
Matrix Name
Identifies the matrix name (STIFFNESS, MASS, or DOFS)
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.
