Issue an INISTATE,WRITE command (available in the solution processor only) to write a set of initial-state values to a file. You can issue the command multiple times to modify or overwrite your initial-state values.
The initial-stress file written by the INISTATE,WRITE command has the same format as that of the input file. The stresses in the file are those calculated at the integration points when the convergence occurs in a nonlinear analysis. If the analysis type is linear, the stresses are those calculated when the solution is finished. An example initial-stress file resulting from this command follows:
