Monitor HYSYS in Task Manager. If memory usage consistently hits 90%+ of installed RAM, your simulation will fall into a "swap file death spiral" — increasing runtime by 100x.
Windows manages virtual memory. If you have 32GB physical RAM, set a on your fastest SSD. HYSYS will overflow to disk gracefully rather than crashing with "Out of Memory."
