Tera Analysis has announced the latest release of its finite-element simulation software, Quickfield.

New features include the ability to import magnetic state in DC Magnetic problems, parallel computing with Label Mover, an improved user interface and a new setup system, which ensures full compatibility with all types of the Windows 7 operating system.

All three editions of Quickfield 5.8 – Professional, Lite and the free Student Quickfield – are available now.

Engineers involved in magnetic system design are aware of the importance of calculating self and mutual inductances.

For non-linear problems with several coils, this task is quite complicated because magnetic parameters of the media depend on the combined action of all field sources in the problem.

Self and mutual inductance calculation is usually achieved by setting up the problems with only one magnetic field inducing current at a time.

Flux distribution in this case is different from a situation when all field sources act together.

In non-linear media this leads to the differences in the magnetic permeability distributions, resulting in loss of accuracy of inductance calculations.

Quickfield 5.8 provides a solution of this difficulty.

Using a familiar coupled problems interface it is now possible to import the exact distribution of the magnetic permeability into a DC Magnetic problem, then calculate the inductances in exact operating conditions.

Label Mover is the Quickfield utility for parametric studies that supports serial calculations, tolerance analysis and optimisation.

It automatically generates and solves groups of Quickfield problems, which often requires considerable time.

With Quickfield 5.8, Label Mover is able to run several Quickfield problems in parallel, utilising all processor cores available on the computer.

Automatically generated Quickfield problems are united in groups for parallel processing.

The number of parallel groups has a default value defined by the number of core processor and can be adjusted by the user.

This feature, combined with the speed of the Quickfield solvers and meshers, offers an improvement in Quickfield’s performance on extremely large parametric analysis problems by enabling users to take advantage of the power of today’s computer systems.

Quickfield 5.8 also offers improvements to the software’s user interface.

A new window for geometric model properties provides better control of geometric objects and simplifies the assignment of physical data and mesh generation parameters.

The Quickfield 5.8 installation procedure is controlled by a new setup system that provides better compatibility with modern operating environments.

It also offers more freedom to IT administrators in the selection of the most appropriate installation options for their end users.
