You can generate matrices representing the following model
structural damping, and
In Abaqus 6.7 use the following option to generate the
stiffness matrix, etc.
*MATRIX GENERATE, STIFFNESS
*MATRIX GENERATE, MASS
*MATRIX GENERATE, VISCOUS DAMPING
*MATRIX GENERATE, STRUCTURAL DAMPING
*MATRIX GENERATE, LOAD
For details see section 10.3.1 of Abaqus Analysis User's
Manual Volume II: Analysis
Generated matrices are output to a text file.
The assembled sparse matrix operator data are written to
the text file as a series of comma-separated lists. Each
row in the file represents a single matrix entry; a row is
with the following elements
1. Row node label
2. Degree of freedom for row node
3. Column node label
4. Degree of freedom for column node
5. Matrix entry
For load matrices, which represent right-hand side vector
data, each row in the text file is written with the
1. Node label
2. Right-hand side vector entry.
