Windows-based finite-element software QuickField v5.2, used for electromagnetic, heat transfer, and stress analysis, includes new analysis options and reduces effort required for initial training from minimal to almost none.

• New problem formulation method: Wide range of problems, including DC, AC, and Transient Magnetics, Electrostatics, DC Conduction, Transient and Steady-State Heat Transfer, Stress, is expanded with the addition of AC Electric Analysis. In this type of problem the objects of study are electric fields, currents, and losses arising in conductors and imperfect dielectrics from the application of alternating sinusoidal voltage or external currents. Postprocessor allows study of voltages, electric fields, conductive and reactive current densities, losses, capacitances, forces, torques, and electric energy distribution. Results may be displayed as color maps, plots, diagrams, or used as heat sources or mechanical loads for coupled temperature distribution or mechanical stress analysis problems.


• New tools for results analysis: New Spatial Harmonic Browser, implemented as a postprocessor add-in, allows the user to calculate and view harmonics (that is, phases and amplitudes for Fourier series) for any parameter plotted along the arbitrary contour. This is often required for electrical motor design, where one of the goals is to decrease losses and sounds by decreasing specific harmonic amplitudes.


• Improved compatibility with CAD systems, other programs: In addition to existing geometric model exchange by DXF file import and export, the new utility (implemented as a Model Editor add-in) facilitates import of SolidWorks sketches directly into QuickField models. Other Windows programs may access the internal functions and data structures of v5.2 via open Object Model. This simplifies embedding QuickField into larger simulation systems, and is used by free tools for parametric analysis and data conversion, distributed along with QuickField.


• Reduced complexity: Finite-Element Analysis is based on the finite-element mesh generation procedure, and mesh quality and density dramatically affect the accuracy of the results. However, mesh creation is something of an art, often confusing to novice users. QuickField v5.2's Model Editor is capable of adaptive mesh refinement based on the results of previously solved problem (a process also known as H-refinement). Although manual and automatic mesh controls still exist, they are rarely needed.


• Dynamic Help utility: Context-related tips and references to other Help sections guide novice users at any stage of problem analysis. Help articles are backed by a Virtual Classroom with interactive tutorials on QuickField basics and Problem Book; additional help is available via QuickField Support website.
