I had a few questions about post processing in NX.
1. I have results from an ABAQUS run in both *.fil and *.odb format. I made the run twice to obtain *.fil files with both stresses at the integration points and stresses at the nodes. The odb file contains both of these by default. I would liek to be able to import the *.odb file into NX, but it says 'Results File Not Found' when I attempt to import it. I chnaged the customer defaults for the ABAQUS results file to be *.odb (weeks ago so I have restarted NX plenty of times). Not sure why this would happen. Could be that the proper ABAQUS libraries were not available to link? I'm at work so I don;t really have control over these things....
2. when I tried to post process in NX, I noticed something peculiar... the stresses are different than what I see in NX IDEAS and ABAQUS CAE Post Processing. It is not a slight difference either (about 30%
). there are several things I can think of, but I think I have ruled most of them out...
[ul]
[li]Coordinate systems: Looks like its in the right place. If I go to 'Set Results' I choose absolute and it appears that the part is in the right place. Side question on this... Is there a way to display the absolute xyz coordinates of a point? It used to be near measure in IDEAS....[/li]
[li]Averaging: Can you control the stress computation in NX. I poked aroudn for a while and I couldn't actually find anything about it. In ABAQUS you can control the % averaging of the results which will change the stress values (0-100%). I can't find this anywhere in NX...[/li]
