is sufficient only for students working on basic, single-unit operation models (e.g., a simple distillation column or flash drum).
RAM is arguably the most important factor for simulation performance. Each unit operation, stream, and property calculation consumes memory. When RAM runs out, the system resorts to using the hard drive as virtual memory, which slows performance dramatically.
These place additional demands on the CPU due to real-time or near-real-time calculations. Extra RAM is also important when running extended dynamic scenarios.
Typically requires .NET 4.8 or later.
