#119: SOL200 – Extract the updated element thickness during topology optimization.

1) To extract the updated (modified) element thicknesses, use ECHO=PUNCH (NEWBULK) in the case control section.

SOL 200
TIME 600
CEND
PARAM,DESPCH,1
ECHO = PUNCH(NEWBULK)
MAXLINES = 999999999
DESOBJ = 1
DESGLB = 1
ANALYSIS = STATICS

2) Read this punch file, which contains updated bulk data into Patran. In the new database, go to File–>Import–>MSC Nastran input–>In the file name tab, type *.pch–>select the punch file –>Hit Apply. This will import all the data into Patran.
