The Simulus Group has a long-standing relationship with OLI Systems (OLI) software. In addition to being an Australian reseller for the software packages, Simulus Engineers can offer consulting services and experience, particularly for hydrometallurgical applications in Stream Analyzer. The OLI software engine is capable of accurately predicting the equilibrium speciation for a wide range of chemical systems, even in highly concentrated, high temperature applications where most software packages fail to make accurate predictions.

In addition to the stand-alone Stream Analyzer software, OLI offers partner products for many of the major process flowsheet simulation packages:
· Aspen Plus

· Aspen Hysis

· UniSim

· ProII
