2D/3D Electric Field Simulation Software

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.

Analyse and predict the performance of:

  • Transformers
  • Insulation Systems
  • EMC Compatibility
  • Bus Bars
  • MEMS

  • High Voltage Components
  • Shielding
  • Cables
  • Capacitive Sensors/NDT
  • Many more
ElecNet uses the finite element method to solve for the electric field strength, forces, capacitances and other quantities. Each module is tailored to simulate different types of electric fields and is available separately for both 2D & 3D designs.

Static fields
  • Simulates static electric fields produced by specified DC voltages and charge distributions
  • Supports floating conductors

Current Flow
  • Simulates the DC current distribution produced by specified DC voltages on electrodes in contact with conducting material

Transient or Time-varying electric fields
  • Simulates transient electric fields produced by transient voltages
  • Non-linear permittivity and conductivity
  • Accounts for displacement currents
  • Supports floating conductors
  • Electrical conduction and lossy dielectrics
  • Second-order time stepping
  • Resume Feature: pause at a particular time step for inspection

AC or Time Harmonic electric fields
  • Simulates electric fields produced by specified AC voltages
  • Analysis based on a single frequency using phasors (complex domain)
  • Accounts for displacement currents
  • Supports floating conductors
  • Electrical conduction and lossy dielectrics

Common Solver Features
  • All solvers are multithreaded for true multicore support
  • Symmetry for reducing solution domain
  • Parametric Module for "What if?" analysis
  • Coupling with ThermNet 2D/3D
  • Optimization with OptiNet


Geometric Modeller
  • Easy to use Extrusion-Based and Solid Modelling tools make even the most complicated designs quick and painless to draw.
  • 3D ACIS Modeler from Spatial, with DXF/SAT imported natively.
  • Additional filters allow CAD files to be imported efficiently, including the coils. Formats include STEP, CATIA, Pro/E, IGES
  • Full Boolean operations and multi-sweep functions for complex geometries

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:
  • Initial force and force direction
  • Charge
  • Mass
  • Energy
  • Dynamic Coefficient of Viscosity (drag force)
  • Optionally account for relativistic effects
  • Angle
Once the simulation is complete, the Trajectory Evaluator reports the following results:
  • Particle Position (chart)
  • Particle Velocity (chart)
  • Particle Acceleration (chart)
  • Position, Velocity and Acceleration at each time step (text file)
  • Trace of particle's trajectory
The Trajectory Evaluator supports the following solver modules:
  • MagNet 3D magnetostatic, time harmonic (AC) or transient solver
  • ElecNet 3D electrostatic solver
  • A combination of magnetostatic and electrostatic fields
A frequency can be set on the particle to allow for AC field simulations with the electrostatic solver.
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.
