Engineering Simulators
Explore engineering systems dynamically. Change inputs, trigger scenarios and watch how physical variables respond over time or through an interactive visual model.

EngineerHub simulators are designed to make system behaviour visible rather than reducing every problem to one static answer. Some model plant or network dynamics; others focus on a single physical phenomenon. Use them for learning, sensitivity studies and preliminary exploration, and follow the linked background sections for assumptions and model limits.
Choose a tool below by purpose. Individual pages include their own assumptions, equations, references and limitations where applicable.
