4.6.7. Example: Node-Based Initial Strain Problem Using the INISTATE Com-

mand

This example node-based initial state problem describes how to generat e a node-based initial state file
from another analysis and then apply that data to a modal analysis.

In step 1, a node-based initial state files is generated. In step 2, the file is read in and a static solution
is generated. In step 3, the modal analysis is done.
