I am using Abaqus Viewer 6.42 on Windows 10 that has had a recent patch update. I keep receiving this error when I try to create a contour plot. "There is no valid step data on the output database. The requested operation has been canceled." I noticed while generating my output files that there is a lock file being generated. I have a deleted the lock file before and regenerated the output files; however, the lock file continues to be generated. I am not sure what is causing this error because my input files that have previously generated the proper output files are not working now.
