Directory for Output Files
Specify the directory where you want Creo Simulate to place the output files, which contain the results data from the run.
Creo Simulate places all output files and the engine input files in a directory called study (study is the name of the design study you are running), and places study in the directory for output files you specify here.
The Run Settings dialog box initially displays the name of the directory you specify using the sim_run_out_dir configuration option, or it displays the current working directory if you do not set the configuration option. The directory you specify appears the next time you open the dialog box.
As a general guideline, you should have 9 to 15 megabytes of disk space available for the output files.
