Easy5

Capabilities

Easy5 is a graphics-based software tool used to model, simulate, and design multi-domain
dynamic systems characterized by differential, difference, and algebraic equations. The systems
that can be analyzed using Easy5 include mechanical, electrical, hydraulic, pneumatic, thermal,
gas dynamics, powertrain, vehicle dynamics, digital/analog control systems and much more.

•tAssemble models easily from hundreds of pre-built

Models may be assembled graphically from special pre-built, ready-to-use multi-domain
system-level blocks such as valves, actuators, heat exchangers, gears, clutches, engines,
pneumatics, flight dynamics, and many more, or from primitive functional blocks, such as
summers, dividers, lead-lag filters, and integrators. The building blocks are packaged in easily
accessible application libraries. Users can also create custom libraries for reuse and sharing
across the enterprise. An open architecture provides an interface to a broad set of software and
hardware tools used in computer-aided engineering (CAE), including Adams®, MSC Nastran®,
Simulink®, and other CAE software tools.

•tComplete system virtual prototyping by linking Easy5

Modeling
The Easy5 interface is developed using Qt and has intuitive point and click interface that has
Windows look and feel on Unix systems as well. The interface is designed to let the users build
even complex models with ease and to maintain multiple libraries and components for reuse. It
uses dockable or floating windows and tool bars and has the ability to easily cut and paste data
from Windows applications like Excel into Easy5.

effectively

Analysis
Easy5 analysis program provides you with the capability to perform a set of linear and nonlinear
analyses on the same executable model.
Nonlinear analysis options include the capability to perform dynamic behavior and steady state
analyses on the system model.
Easy5 can also generate a linear approximation of a nonlinear model to provide insight into the
stability and performance of the nonlinear system at various operating points. The variety of
linear analysis tools available include:
•tTransfer function analysis: Permits you to calculate the poles, zeros, leading coefficient and
frequency response between any two points in your system model
•tRoot locus analysis: Provides you with the capability to determine the locus of the system
model eigen values as a function of any system variable.
•tEigen value sensitivity analysis: Measures the sensitivity of system eigen values to changes in
a user specified system parameter
•tStability margins analysis: Calculates the maximum and minimum values for user specified
parameters which maintain system stability
•tLinear model generation analysis: Used to calculate complete linear model and also compute
the eigen vectors of the linear model.

•tReduce CAE cost with shareable libraries
•tImprove CAE effectiveness by integrating with
other tools
