ElecNet

ElecNet 2D/3D is the leading electric field simulation software tool. Designers can easily model the most complicated devices and accurately predict their behaviour. Based on finite element analysis methods, ElecNet solves static, AC and transient electric field and current flow problems.

Overview

Applications

Analyse and predict the performance of:

- Transformers

Material Library

- Pre-defined library of linear, nonlinear and anisotropic materials
- Advanced loss computation based on Steinmetz equation
- User-defined materials easily added with Material Editor & curve fitting utilities
- Simple Drag-and-Drop applies a material to any part of the model, which is then stored with the model.

Meshing & Adaption

- Adaptive strategy determines where refinements are needed after each step by:
- Subdividing elements (2D/3D)
- Increasing the polynomial order (3D)
- Both techniques combined (3D)

- Mesh layers for skin depth analysis and highly anisotropic volume elements
- Separate mesh for coupled thermal problems (with ThermNet)
- Motion Re-mesh region for more efficient meshing process
- Extensive manual meshing controls

Parametric Studies & What-if Analysis

- Perform multiple experiments for "What if?" analysis
- Any quantity can be parameterised (e.g. geometric features, materials, mesh settings) and can be varied through a user-specified range of values
- Multi-parameter solutions, with automatic display of solution vs. Parameter values (including animations).

Customisation & Interoperability

- Powerful scripting allows MagNet to work with any programming environment that implements ActiveX scripting and OLE Automation (such as Visual Basic Script, Java Script, Perl, etc.).
- ElecNet can then be coupled to any Active-X compliant application such as Microsoft Office, Matlab, MathCad, AutoCAD etc.

- Automate repetitive tasks
- Link to third party software such as Excel® or MatLab®
- Customize ElecNet for your needs

- Field probing
- Export to Excel

Trajectory Evaluator - Predicting the trajectory of a charged particle over time.

The Trajectory Evaluator is used with MagNet and ElecNet to simulate the path of one or more particles while under the influence of electromagnetic or electric fields.

Typical applications which require combining field solutions with particle trajectory calculations include: beams (electron and ion guns), filtration, precipitators, ion traps, deflector plates and more.

The particles are first characterized by specifying the following parameters:

OptiY - Use with MagNet to perform optimisation and sensitivity analysis on any electromagnetic device.

Based on a long research and development at Dresdner University of Technology in Germany from the early 1990, OptiY GmbH has been founded in 2006. The mission is to develop and promote the software OptiY® and to help all engineers making their product development better, faster and cheaper.

OptiY® is an open and multidisciplinary design environment providing most modern optimization strategies and state of the art probabilistic algorithms for uncertainty, reliability, robustness, sensitivity analysis, fatigue life prediction, data-mining and meta-modeling. The simulation system can be considered as black box with inputs and outputs. Within, it is an open platform for different kind of model classes. The adaptation to a special simulation environment takes place by a suitable interface. Collaborating different simulation systems is possible as networks, finite-element-method, rigid body dynamics, also material test bench as control optimization for drives. Use OptiY with MagNet to perform optimization and sensitivity analysis on any electromagnetic device.

Two case studies, Robust Design of Induction Motor and Tolerance Analysis of Surge Arrester, which demonstrates the linking of these products, can be viewed on OptiY's web site.
