The Electrostatic module may be used for simulation of electric fields, caused by known charges and voltages distribution. The fields should be static - this means that no currents or varying voltages may be defined or analyzed. Electric field in these non-static situations may be simulated using DC and AC conduction modules, or Transient Magnetic module, depending on the problem formulation details. Electrostatic simulation in QuickField includes possibility to analyze the trajectories of the charged particles in the electric field.
The Electrostatic module can be used to design and analyze insulation systems, cables and capacitors, electronic tubes, high-voltage equipment. It is also used for EMC compatibility, biomedical researches, and variety of other applications.
Starting from version 6.0 Electrostatic analysis may be performed in plane-parallel, axisymmetric and 3D extrusion formulations. Starting from the version 6.1 3D analysis capabilities are expanded by the possibility to import 3D geometries from CAD systems in STEP format.
Electrostatic module features:
- Anisotropic permittivity
- Distributed and concentrated charges
- Floating conductors
- Dirichlet or Neumann boundary conditions
- Results: Voltage, electric field, electric displacement, capacitance, electric gradients, forces, torques and other integral quantities, particles trajectories*
- Couplings*: the electric forces can be used for stress analysis on any existing part (electro-structural coupling)
* This feature is currently available for 2D formulations only.
