Parametric porosity simulations can use significant disk space in the Temporary and Application Data directories. Disk usage increases exponentially with cube size. A typical 1 mm cube requires about 1.5 MB per permutation. A 3 mm cube requires 5 MB per permutation plus an additional 120 MB in both the Temporary and Application Data folders. A 10 mm cube requires 2 GB per permutation plus an additional 60 GB in both the Temporary and Application Data folders. Data sizes are approximate and will vary based on simulation parameters.

Consider changing the Temporary Data and Application Data directories to a larger disk if needed, accessible under Edit > Settings.

Also, after a Porosity simulation is complete, it is good practice to save the Porosity Summary .csv file and then delete the Porosity simulation by using the Delete button in the UI. Do not attempt to delete simulations directly from within the AppData folder structure because you could corrupt the Additive database.
