Develop your chemistry and thermodynamic understanding
This course offers comprehensive training in OLI Corrosion simulation techniques using the OLI Studio: Corrosion Analyzer. Participants will explore the fundamental principles of corrosion modeling, guided by OLI’s software tools, and their underlying chemistry and thermodynamic frameworks.
Pre-requisite: Basic knowledge of OLI Studio: Stream Analyzer.
OLI SYSTEMS ONLINE TRAINING
What to expect from the training course
This workshop will teach electrolyte chemistry and corrosion concepts, as well as how to navigate the OLI Software interface. At the end of the course, participants will be able to formulate and build their own applications and interpret the data presented in reports and plots.
WHO SHOULD ATTEND
The course is designed for beginers and prospective OLI clients
The class is designed for participants with little or no knowledge of OLI simulation techniques. Intermediate level clients wanting to refresh their skills may also join this class; there are extra problems in each section that allow for independent inquiry.
