In ANSYS Release 11.0, does issuing the SET command overwrite boundary conditions stored in the database?

Yes, when the SET command is issued, displacement and force boundary conditions (D and F commands) are replaced by the corresponding values on the results file. In a single-load-step analysis these values are usually, but not always, identical. One situation where they can differ is with axiharmonic elements. /POST1 changes the applied boundary conditions to create consistent plots. To preserve the database boundary conditions, save the database before entering /POST1 and RESUME it after leaving /POST1.
