# What's New in QuickField 4.3

This article is addressed to users of previous versions of QuickField. It contains brief description of new options and capabilities. Since all these features are described later in more details, you can skip this section, if you are new to QuickField.

The main new features introduced in QuickField 4.3 are:

- ActiveField™ Technology and
- New Setup utility.

## ActiveField Technology™

ActiveField (TM) Technology extends the possibilities of usual FEA program by converting it to a flexible development platform for engineering applications.

In addition to the features of previous QuickField versions ways of your control over our software are not restricted by its graphical user interface any longer. You also could develop your own custom-made applications, interacting with QuickField core through Automation (former known as OLE Automation).

The most important benefits of ActiveField technology:

- Repetitive tasks automation.
  Example: performing of calculations with incremental values of model parameters.

- Parameterized geometry definition for specific model classes.
  Example: Parameterized geometry description of electric motors using standard geometry fragments (slots, coils, cores) for QuickField geometrical model generation.

- Specific results calculation automation.
  Example: Specific calculation can be programmed to obtain inductances and power losses of electric motor. Another example is capacitance matrix calculation for system of conductors of multi-layer PCB.

- QuickField field simulation as a part of more complicated task.
  Example: electrical circuit parameter optimization with QuickField simulation to obtain coil inductance for each iteration of optimization algorithm.

- QuickField using together with MS Office, MatLab, AutoCAD and other specific tools for solving particular task in the common development environment.

Most of modern development environments supports this technology. Among them are Microsoft Visual Basic, Visual Basic for Applications, Visual C++, Borland Delphi and many other.

The core components of the ActiveField Technology are QuickField Object Model, ActiveField Techonlogy Examples and QuickField Parametric Workbench:

- QuickField Object Model - a set of objects for field simulation problem defining, solving and analyzing. They allow to create a new QuickField problem, describe the geometric model, build the mesh, solve the problem and analyze the results in such a way as it can be done interactively using the QuickField graphical user interface.

> The QuickField Object Model is implemented as COM Automation classes and interfaces. Therefore, scripting languages like Microsoft Visual Basic as well as Visual J++ and Visual C++ applications can access the QuickField objects.

- ActiveField Technology Examples demonstrate usage of the Quickfield Object Model from within different container environment: Microsoft Word, Microsoft Excel, and stand-alone Visual Basic application. In your ActiveField folder you can find:

> 1. The Magn1 Tutorial consisting of three lessons. Each lesson explains how to define and solve our old Magn1 example utilizing several possible approaches of ActiveField technology.
> 2. Three more advanced examples demonstrate ActiveField use with Microsoft Word (Cable sample), combination of different analysis types (Slot-Tooth sample) and Workbench use for a real world problem - design of the switched reluctance motor (SRM sample).

- QuickField Parametric Workbench is an environment helping you to create and play with most typical application of ActiveField. It consists of:

> 1. Workbench Wizard for interactive authoring a Microsoft Visual Basic 6.0 code. Each module implements a parameterized model with predefined set of input and output parameters.
> 2. Workbench application for running several models with different input parameters.
