Nonlinear Buckling
Nonlinear Buckling
(OP)
Hi,
I'm trying to run a nonlinear buckling analysis in ANSYS 12.
The linear buckling analysis results are stored in ..\SYS-1\MECH\file.rst. I've duplicated the original static analysis, and placed a "Commands" object under the duplicate's Static Structural branch. The "Commands" object contains the following:
/PREP7
UPGEOM, 0.01,,'D:\xxxxxx Rus_files\dp0\SYS-1\MECH\file', rst
/SOLU
The execution throws a warning telling me that the result file D:\xxxxxx.. cannot be opened.
I can't figure out what's wrong and I would be very grateful if you could help me set it up properly.

RE: Nonlinear Buckling
you have to save your analysis before updating the geometry.

That's a tutorial on how to get a non-linear buckling analysis done.
I have a question of my own, has any of you performed a non-linear load-based analysis? I ask this because, it seems to be that to observe plastic behavior, it can only be done by performing a displacemente-based analysis. If anyone can help me, i would be more than grateful.
Best regards!
