ElecNet2D/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 behavior. Based on finite element analysis methods, ElecNet solves static, AC and transient electric field and current flow problems.

Analyze and predict the performance of:

  • Transformers
  • Insulation Systems
  • EMC Compatibility
  • Bus Bars
  • MEMS
  • High Voltage Components
  • Shielding
  • Cables
  • Capacitive Sensors/NDT
  • Many more



Recent Improvements

  • Speedups to allow the use of many electrodes in a model (more than 2x faster)
  • Improved waveform editor
  • Coupling with ThermNet
  • Better visualization of field and arrow plots
  • Improved graphing feature
  • Improvements to the automatic meshing

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.
