An incredible, free, and open-source chemical process simulator. It features an extensive database of chemical compounds, advanced thermodynamics (Cape-Open compliant), and a user interface very similar to HYSYS.

In the engineering world, accuracy is everything. Using a "crack" might save money today, but a single calculation error caused by a faulty bypass can lead to catastrophic design failures. For learning and reliable simulation, is the truly "better" alternative to seeking out pirated software.

AspenTech often provides temporary trial licenses for those enrolled in their official training modules.
