Complete the Bulk Data File

Before the analysis is completed, we must remove some of the unnecessary entries in the bulk data file and modify the SUBCASE.

1. Remove the NASTRAN SYSTEM(316)=19 line from the bulk data file.
2. Locate the SUBCASE 1 entry in the bulk data file.
3. Remove the STEP 1 and ANALYSIS = NLSTATIC lines within the SUBCASE 1 entry.
4. Change the NLPARM = 1 line to NLSTEP = 1.
5. Add the following output requests below the LOAD = 1 line:

   DISP = ALL
   GPFORCE = ALL
   NLSTRESS (PLOT,NLOUT=101) = ALL

   These three lines specify additional output for post-processing.

6. Remove the following lines:

      DISPLACEMENT(SORT1,REAL)=ALL
      SPCFORCES(SORT1,REAL)=ALL
      STRESS(SORT1,REAL,VONMISES,BILIN)=ALL

   These three lines are unnecessary since we just specified additional output requests in step 5.

7. Remove the following lines:

   PARAM   PRTMAXIM YES
   PARAM    LGDISP  1
   NLPARM   1                       AUTO            25      UPW     NO

   We can remove the PRTMAXIM parameter since we don't require a printout of maximum applied loads, single-point constraints, multi-point constraints, or displacements. We don't anticipate large geometric effects for the small displacement loading of the plate, therefore the use of LGDISP is unecessary. We already used the NLSTEP entry to define our analysis step, therefore the NLPARM entry is not needed.

8. Save the changes to the bulk data file.
