SUMMARY

The Abaqus CAE 'KeyError' issue arises when attempting to create reports from xy data, specifically resulting in 'KeyError:RF' or 'KeyError:U'. This problem is identified as a bug in Abaqus version 6.8.1, which is resolved in version 6.8.3. Users without admin privileges on their network can work around this issue by re-selecting nodes and utilizing the XY Data Manager to extract plotted numbers manually. This method allows users to bypass the bug and obtain the necessary data for reporting.

PREREQUISITES
  • Abaqus CAE 6.8.1 or later
  • Understanding of ODB field output
  • Familiarity with node selection in finite element analysis
  • Basic knowledge of data extraction techniques in Abaqus
NEXT STEPS
  • Research the differences between Abaqus versions 6.8.1 and 6.8.3
  • Learn how to effectively use the XY Data Manager in Abaqus
  • Explore troubleshooting techniques for common Abaqus CAE errors
  • Investigate alternative methods for data extraction in finite element analysis
USEFUL FOR

Finite element analysts, Abaqus users encountering data extraction issues, and engineers needing to generate reports from simulation results.

I've done a very simple analysis of a truss in Abaqus CAE. I want to create a report of the xy data, but every time I try I'm confronted with 'KeyError:RF', or 'KeyError:U', depending on which xy data I'm trying to get at.

My search of google and Abaqus' online help has only led me to one guy who says this is a bug in Abaqus 6.8.1 and is fixed in 6.8.3. This is no use to me as I'm working on a network without admin privileges.

Does anyone have any insight?

thanks in advance
 
Engineering news on Phys.org
1 Create xy data
2 ODB field output
3 Select node
4 Select type of plot ie Unique nodal
5 Plot results

(If it doesn't work first time the node selection has gone so select again)

Then to get the actual numbers go to XY data manager tehn the plot should show, go to edit and you'll find the numbers that were plotted, highlight and copy these to excel. This is a way to get round the bug
