For a smooth experience with large-scale simulations or dynamic modeling, aim for the "Recommended" specs rather than the bare "Minimum." Processor (CPU): Intel Core i5 family (2.8 GHz) or faster. Recommended: Aspen Plus Minimum System Requirements | PDF -

HYSYS benefits significantly from high single-core clock speeds (3.5 GHz+). While it does support multi-threading for certain solver tasks, a faster individual core is often more beneficial than having dozens of slower cores. 2. Random Access Memory (RAM)
