Dear Duoxin,
You can reference the menu - Basic Guide, Chapter5, The General Postprocessor (Post1), it describes the detail procedure to output the path to the file. You can use EXCEL to retrive the file. Part of menu regrading your question is listed below,
5.3.4.7. Archiving and Retrieving Path Data to a File
If you wish to retain path data when you leave POST1, you must store it in a file or an array parameter so that you can retrieve it later. You first select a path or multiple paths and then write the current path data to a file:
Command(s):
PSEL
GUI:
Utility Menu> Select> Paths
Command(s):
PASAVE
GUI:
Main Menu> General Postproc> Path Operations> Archive Path> Store> Paths in file
To retrieve path information from a file and store the data as the currently active path data, use the following:
Command(s):
PARESU
GUI:
Main Menu> General Postproc> Path Operations> Archive Path> Retrieve> Paths from file
You can opt to archive or fetch only the path data (data mapped to path (PDEF command) or the path points (defined by the PPATH command). When you retrieve path data, it becomes the currently active path data (existing active path data is replaced). If you issue PARESU and have multiple paths, the first path from the list becomes the currently active path.
Sample input and output are shown below.
/post1
path,radial,2,30,35 ! Define path name, No. points, No. sets, No. divisions
ppath,1,,.2 ! Define path by location
ppath,2,,.6
pmap,,mat ! Map at material discontinuities
pdef,sx,s,x ! Interpret radial stress
pdef,sz,s,z ! Interpret hoop stress
plpath,sx,sz ! Plot stresses
pasave ! Store defined paths in a file
finish
/post1
paresu ! retrieve path data from file
plpagm,sx,,node ! plot radial stresses on the path
finish |
