Electromagnetic simulations are critical to electrical and electronic product
designs across many industries. Applications involve everything from rotating
machines (motors and alternators), sensors and actuators, power generators
and transformer systems, and Micro Electro Mechanical Systems (MEMS). ANSYS
Emag provides a comprehensive range low-frequency analysis features to address
the diverse needs of the electromagnetics engineer, from motor design to ion
optics.

FLUX is a CAE software package for electromagnetic design, which utilizes finite element (FEM) analysis. FLUX includes full geometry parameterization capabilities, static and dynamic excitation capabilities, connection to internal or external electrical circuits, and linear and rotating motion capabilities. FLUX technology enables you to explore, evaluate, and understand the behavior of a device that contains nonlinear steel components, electric currents in conductors, and/or permanent magnets.
FLUX can be used in the research, design, and production of every type of electric device and process, from small appliances to large machinery, from audio speakers, to medical MRI. Coupled with other programs, FLUX solutions expand into drive technology, fluid power, mechanics, acoustics, and thermal analysis. FLUX offers a direct link to Simulink, enabling you to develop your control strategy directly in Simulink with the FEM model described in FLUX. During the computation, FLUX and Simulink are run in transient cosimulation.

SimMechanics is an extension of a great "system oriented" simulation
package : Simulink. In Simulink your system is modelled as connected
blocks which define "transfer functions" between inputs and output.
Each of your parts and each of your joints will be converted in a
block by the cad-2-simmechanics tool, then you'll complete the diagram
by adding source signals, feedback loops and automation devices in a
much more comfortable manner than coding in adams.
A very interesting alternative to Simulink is Dymola by http://www.dynasim.com/
,which relies on an open-source language called Modelica http://www.modelica.org/.
It'd definitely be my choice for complex systems.
Block diagram oriented simulation is in trouble with contact problems,
for example when a part is in a conveyor and falls on another device.
You'd need to define all the possible contacts as blocks, while 3D
tools such as CosmosMotion use general collision (interference)
detection. However, Block diagrams allow to model contacts and
friction with much higher detail than the "impact" model used in 3D
(CosmosMotion). The combination of the general collision detection
with impact forces and frictionresults in long simulation time and,
quite often, wrong results.
A difficulty with all tools including CosmosMotion is the conversion
of assembly "mates" into cinematic joints (revolute, prismatic...),
while handling "flexible" assemblies and other cad-related stuff. It
works on simple models where mates have been carefuly defined using
gormetry on connected parts. If your model has "design mates" such as
the distance between reference planes of two distant parts, or if you
didn't select the same parts to define the concentricity and the
coincidence of a revolute joint, or didn't block the free motion of
your screws, prepare to spend some time clearing the jungle of the
cinematic joints...
Hope this helps.

Electronic Business using eXtensible Markup Language, commonly known as e-business XML, or ebXML (pronounced ee-bee-ex-em-el) as it is typically referred to as, is a family of XML based standards sponsored by OASIS and UN/CEFACT whose mission is to provide an open, XML-based infrastructure that enables the global use of electronic business information in an interoperable, secure, and consistent manner by all trading partners.
The ebXML architecture is a unique set of concepts; part theoretical and part implemented in the existing ebXML standards work.
The ebXML work stemmed from earlier work on ooEDI (object oriented EDI), UML / UMM, XML markup technologies and the X12 EDI "Future Vision" work sponsored by ANSI X12 EDI.
The melding of these components began in the original ebXML work and the theoretical discussion continues today. Other work relates, such as the Object Management Group work and the OASIS BCM (Business-Centric Methodology) standard (2006).
