Hi,nI am running a very complex nonlinear analysis which requires a lot of hard disk memory during the simulation. I was wondering if it is possible to delete the ProjectScratch folder during the simulation process without corrupting or compromising the simulation. What is the aim of that folder?nThank you.n

nThe scratch folder is not supposed to be deleted until ?emptied? by WB when it moves the result files from the scratch folder into the proper WB project Mech folder. nThe _ProjectScratch directory is a temporary directory that is created during the solve, where files are copied to _ProjectScratch and then copied back from _ProjectScratch upon completion of solve. It should be automatically deleted by ANSYS upon solving, or even when a user Interrupts or stops solve. However, when the system crashes, the _ProjectScratch directory does not get automatically deleted. The files can be used to recover from a crashnGenerally if you have saved an analysis and closed ANSYS, then ANSYS no longer needs the _ProjectScratch folder and it can be deleted via Windows Explorer, etc. This is especially true if the simulation has been archived.n

Yes, finally I've tried to delete the Project Sctrach folder without success since simulation was running meanwhile. As you said at the end of the simulation that folder disappeared. However I thought that temporary files were stored in the Temp folder in a directory visible in the options of Workbench. So I couldn't understand why two temporary folders for one simulation. Moreover since the project scratch folder increases in size during the simulation I experienced an abrupt stop of the simulation and closure of Ansys due to the poor hard disk space. Thus, I would like to know if it is possible to understand before launching a simulation the amount of hard disk required to complete the analysis. The solver output mentions something about in core and out of core memory, what about that? nThanks.n
