Understanding equation-oriented simulators
There are essentially two process simulator technologies: modular (sequential) and equation-oriented (simultaneous). In this video (in Portuguese) some of the advantages of the equation-oriented approach are shown for the iiSE simulator.
iiSE intro tutorial
The iiSE process simulator is an equation-based simulator. This leads to some differences in use, when compared to the classical sequential-modular simulators. With this short tutorial below you will learn how to build your first simulation with iiSE:
