Define Solution Output with a Text Editor

Now that we have defined a nonlinear load step and nonlinear solution controls, we are ready to specify output to the results file. To examine the fiber and matrix damage states generated by Simulation Composite Analysis, we must first request state dependent variable (SV) output to the results file.

1. With the bulk data file open, locate the LOAD = 1 line. Below this, add the following:

      NLSTRESS (PLOT,NLOUT=101) = ALL

2. Now locate the NLSTEP entry from the previous page and below it, add the following:

   NLOUT, 101
   , ESV, SV2, SV3, SV4

   Together, these three lines will allow us to examine the fiber and matrix failure indices and the composite damage state for our Simulation Composite Analysis composite material.

3. In order to view these results in Patran, we must add the following line:

   PARAM, POST, 1

Now the bulk data file should appear similar to what is shown below:

SUBCASE 1
   NLSTEP = 1
   SPC = 2
   LOAD = 1
   NLSTRESS (PLOT,NLOUT=101) = ALL
$
BEGIN BULK
$
NLSTEP, 1, 1.0
 , GENERAL, 1000
 , FIXED, 100,
 , MECH, PV, , 0.005
$
NLOUT, 101
, ESV, SV2, SV3, SV4
$
PARAM, POST, 1
$
