is the hard disk full?
where are you saving the results?
what operating system are you using?
if you aren't working locally, start there.
Sorry... I should have provided a bit more information.
1. The hard disk is not full.
2. Saving the results to the 'temp' folder on 'c' drive.
3. Windows 7- 64 SP1
I have, an attempt to narrow down potential issues, moved the necessary part and assembly files to a local drive.
so they were on a network drive initially?
check that the study is set to save the results to a local drive
also what variant of windows are you using? home? pro? ultimate?
is this happening on all parts and assemblies? what happens if you run an analysis on a simple block?
Not enough moving necessary party, copy all parts.
My suggestion move all parts of assembly to dekstop , use pack and go with adding prefix to all parts name.
And re-run the works.there will be no problem
