After I launch the analysis, the program completes some of the processes, and then comes up with the message:
*** STAADPro ERROR MESSAGE ***** Read/write Error in Unit No. 17++ Calculating Joint Displacements. 16:24:21
What does this error mean, and what can I do to avoid it?
This is very likely due to the fact that you have run out of disk space, particularly on the drive which is being used for the SET TEMP environment variable in NT and 2000 operating systems. Since this is usually the C: drive, you need to increase the free space available on the C drive, or whichever is being used for SET TEMP.
