I have a problem when running a static load analysis in Solidworks Premium 2012 sp5.  I start out with a 3,000 KB file.  Every time I run the static analysis the file size more than double as well as the time it takes to start the next analysis.   After the 4^th run the file size is over 105,000 KB and It takes over 8 hours for the analysis to start.  Once the analysis starts it takes maybe 15 minutes at most to finish. Any Idea why the file size is exponentially growing?
