Enhance your understanding of upstream electrolyte simulation
The OLI Studio: ScaleChem modeling course is designed to train attendees on how to use OLI software for upstream electrolyte simulations. Participants will learn how to set up scaling problems, will learn how to formulate and build their own applications and to interpret the data presented in reports and plots.
OLI SYSTEMS ONLINE TRAINING
What to expect from the training course
This workshop will teach upstream electrolyte chemistry concepts and electrolyte simulation techniques using a training manual that starts by modeling a single well. The chapters get progressively more advanced as participants learn more features about the software.
Who should attend
The course is designed for beginers and prospective OLI clients
The class has been developed 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.
