What's new in QuickField 5.7

Release date: January 2010

Version 5.7 expands functionality of QuickField for the electric fields simulation, and also features updated user interface, including new design of windows, panels, toolbars and menus.

1. Transient Electric Field Analysis

Previous QuickField versions included three different formulations of the electric field calculation problem. New formulation introduced in QuickField 5.7 complements these possibilities with simulation of the transient electric field in the non-linear conductive dielectric media:

Analysis type Dielectric permittivity Conductivity of
non-ideal dielectrics
Time dependency
Electrostatics Block-wise
- -
DC Conduction Block-wise
AC Conduction Time-harmonic sources. Field parameters magnitude and phase are calculated.
Transient electric field

Dependent on the electric field E

Arbitrary time-dependent field sources create time-varying field.
Field parameters are calculated for any instance within predefined time range.

New problem formulation may be used for study of the field distribution in the objects subjected to the pulse source (e.g. lightning-induced overvoltage). It may be also applied for designing of the modern insulation constructions, which include non-linear field equalizing elements, varistor overvoltage protection and other non-linear effects.

3. ActiveField Additions

New ActiveField object and functions provide access to material properties and boundary conditions related to new transient electric problem formulation, as well as getting results of this analysis.
