Standard libraries Standard libraries Toolkits The CONTROL library provides a wealth of components with which to model any current control structure covering analogue, digital and mixed systems. CONTROL The THERMAL library allows the modelling of a continuous medium as a discrete thermal network of nodes linked by conductors. THERMAL The ELECTRICAL library contains the basic components for building electric and electronic systems. ELECTRICAL The MECHANICAL library contains components to model 1-dimensional translational and rotational mechanical systems. MECHANICAL
