Dassault Systemes Dynasim Dymola 7.0

Dymola, Dynamic Modeling Laboratory, is
an environment for modeling and
simulation of integrated and complex
systems.

Multi-engineering

Dymola has unique multi-engineering
capabilities which means that models can
consist of components from many
engineering domains. This allows for
models of complete systems that better
depict reality.

Libraries in many different engineering
domains are available that contain
components for mechanical, electrical,
control, thermal, pneumatic, hydraulic,
power train, thermodynamics, vehicle
dynamics, air -conditioning, etc.

The multi-engineering capabilities of
Dymola empower you to model and
simulate any physical component that can
be described by ordinary differential
equations and algebraic equations.

Intuitive modeling

Dymola's graphical editor and the
multi-engineering libraries make
modeling easy. The libraries include
elements corresponding to physical
devices which are simply
dragged-and-dropped to build the model.
Interactions between the components are
conveniently described by graphical
connections that model the physical
coupling of the components. This means
that models are intuitively organized the
same way as the physical system is
composed.

Open and flexible

The Dymola environment is completely
open in contrast to many modeling tools
that have a fixed set of component models
and proprietary methods for introducing
new components. Users of Dymola can
easily introduce components that match
the user's own and unique needs. This
can be done either from scratch or by
using existing components as templates.
The open and flexible structure makes
Dymola an excellent tool to simulate new
or alternative designs and technologies.
Dymola is based on Modelica«, which is
an object-oriented language for physical
modeling developed by the Modelica
Association.

Symbolic Manipulation

Dymola has unique and outstanding
performance for solving differential
algebraic equations (DAE). The key to
high performance and robustness is
symbolic manipulation which also handles
algebraic loop and reduced
degrees-of-freedom caused by
constraints. These techniques together
with special numerical solvers enable
real-time Hardware-in-the-Loop
Simulations (HILS).
