Printing bulk data in your results file

Use the Bulk Data Echo Request modeling object to control whether Nastran prints the bulk data section of your input file in the results file. For example, you can control:

• Whether the software prints the bulk data to the .f06 results file, to the ASCII punch (.pch) file, or to both files.

• Whether the software prints updated bulk data from optimization (SOL 200) analyses.

For example, if you use a Bulk Data Echo Request to print out the updated bulk data output from a SOL 200 analysis, you can then merge that bulk data into the input file for a subsequent analysis.

The options in the Bulk Data Echo Request dialog box correspond to the describers for the Nastran ECHO case control command.
