Use this restart dump if you want to restart the
dynamic relaxation and re-converge to a tighter tolerance
Use the next restart dump to restart as a transient analysis
ASCII File drdisp.sif written at end of dynamic relaxation.
This file contains nodal displacements, rotations and temperatures.
The file may be used for stress initialization - See
