Easy5

Companies world-wide reduce their time to market and development costs using Easy5 - advanced software for multi-domain modeling and simulation of dynamic physical systems. Dynamic systems, those systems whose behavior as a function of time is important, are typically defined using first-order differential (or difference) equations. Easy5 simplifies the construction and analysis of such systems by means of a graphical, schematic-based application, offering a comprehensive set of pre-packaged "components", stored in application-specific libraries, to simplify the assembly and simulation of such systems. Systems engineers work within a familiar schematic drawing environment to add and specify simple, yet complex, connections between components in an intuitive, simple-to-use, multi-level hierarchical modeling environment.

Typical applications of Easy5 include control systems, hydraulics (including thermal effects), pneumatics, gaseous flow, thermal, electrical, mechanical, refrigeration, environment control, lubrication or fuel systems, and sampled-data/discrete-time behavior.

Work with libraries of ready-made components
Easy5 comes with extensive application-specific libraries of pre-built components enabling a variety of dynamic systems to be modeled and simulated quickly and easily. In Easy5, systems can be modeled using mathematical abstractions (summers, dividers, wave generators, and so on), pre-defined components that represent complex physical elements (pumps, gears, valves, heat exchangers, and so on), empirical data (multi-dimensional tables, functional, etc.), and user-defined code. Third-party libraries available from Ricardo offer additional capabilities in modeling power trains, internal combustion engines, fuel-cell, and hybrid vehicle systems.

Access powerful analysis tools
Another powerful aspect of Easy5 is its analysis tools, which allow nonlinear simulation, steady-state analysis, linearized analyses, control system design, data analysis and plotting. Easy5 contains some of the best numerical solvers available, specially designed to handle some of the toughest non-linear problems like stiction, hysteresis, and hard-limiting efficiently resulting in accurate answers quickly. An open architecture provides links to a broad set of popular computer-aided engineering software and hardware tools.
