Utilizing CAE for Electric MotorsPrecise Verification of Performance
A large amount of computation is conducted in parallel by distributed processing.CAE is getting applied to precisely evaluate losses and coupling with thermal effects.

Systems are:• Dynamic: they move, transmit, convey, transform, emit,
measure, ...
• Multi‐Domain: product behaviors span multiple engineering domains & physical phenomena that interact with one another
• Uncertain: they under/over perform, they interact with the environment, they drift, they fail...
• Multi‐Disciplinary: conception through production spans engineering and organizational disciplines and processes

Modelica Significance
Modelica is a standard languageused to model behavior of complex, multi‐domain systems
Modelica is an expanding collection of librariesused to model applications in automotive, aerospace, industrial equipment, energy, and more
Modelica is a vibrant, global communityof users and contributors in industry, research and academia
25 © 2014 ANSYS, Inc. October 7, 2014
Modelica advances our Vision
Today, Simplorer provides:1. Strongest focus and capabilities for electrical and
electromechanical system analysis
2. Tight connections with best‐in‐class embedded SW design (SCADE) and detailed simulation (ANSYS 2/3‐D)
3. Interoperability with the broadest set of languages, interfaces, and libraries
With the addition of Modelica:1. Allows us to extend competency to new domains (e.g. Fluid,
Mechanical), and bring a tighter link with VHDL‐AMS
2. Gives us opportunity to bring the E/E perspective to the Modelica community
26 © 2014 ANSYS, Inc. October 7, 2014
Enabling System Virtual Prototyping
ANSYS has signed an agreement with Modelon to license their Modelica compiler and to integrate it into Simplorer
Key Modelon Technologies:
• Modelica compiler – the Optimica Compiler Toolkit
• Model Libraries – Spanning many domains and industrial applications
