During the analysis of a large model, the analysis engine stops with the error message:
*** STAAD.Pro ERROR MESSAGE ***
** Read/write ERROR in Unit No. 17
*** ERRORS IN SOLVER ***
Even though the hard disk may have plenty of free space, the problem might be caused by the fact that the disk is formatted with the FAT32 format. This format has a file size limit of 4.2GB. So although there is enough disk space, the single file size limit is exceeded for the STAAD solved matrix file (.L17).
You can determine the type of formatting in effect for your drive by going through the following simple steps.
- On your Windows Desktop, go to My Computer.
- Select the drive which serves as the repository for your SET TEMP settings on your machine. If there is only one hard drive on the machine, it will be that drive.
- Right click on the drive and select Properties
- Make sure the file system is NTFS
- Make sure there is enough Free space
If the above also indicates FAT32, you need to find a computer that has its disk formatted with the NTFS format (which does not have a file size limit). Most new Windows XP based computers have the NTFS format.
