Electrostatic analysis is used to design or analyze variety of capacitive systems such as fuses, transmission lines and so forth. Generally the quantities of interest in electrostatic analysis are voltages, electric fields, capacitances, and electric forces.
QuickField can perform linear electrostatic analysis for 2D models (plane or axisymmetrical) and 3D models. The program is based on Poisson's equation. Following options are available for electrostatic analysis:
Material properties: air, orthotropic materials with constant permittivity.
Loading sources: Voltages, and electric charge density.
Boundary conditions: Prescribed potential values (Voltages), prescribed values for normal derivatives (surface charges), and prescribed constraints for constant potential boundaries with given total charges.
Postprocessing results: voltages, electric fields, gradients of electric field, flux densities (electric displacements), surface charges, self and mutual capacitances, forces, torques, and electric energy.
Special features: A postprocessing calculator is available for evaluating user-defined integrals on given curves and surfaces. Floating conductors with unknown voltages and given charges can be modeled. The electric forces can be used for stresses on any existing part (electro-structural coupling).
3D analysis limitations: current QuickField version does not support the anisotropic materials and coupled problems in 3D Electrostatic analysis.
