QuickField Tools
A list of online calculators and scripting tools that extend QuickField's functionality.
These tools are provided “as is” in source form — they can each perform their specific task, and can also serve as examples and templates for your own QuickField programming. They are not necessarily production quality, and documentation is limited.
Depending on the technology used, a tool may run inside QuickField (an add-in shipped with the software), run standalone and interact with QuickField on any Windows machine (a .vbs file), or require a third-party application to run (VBA requires Microsoft Office).
Online Calculation Tools
B-H curve temperature interpolationA ferromagnetic material's magnetic properties vary with temperature, so its B-H curve differs at different temperatures. This tool takes several sets of B-H data at different temperatures and generates an interpolated B-H curve at any specified temperature.
B-H curve permeability calculationConverts B-H curve units and computes differential permeability.
Equivalent B-H curve for laminated coresFor electromagnetic simulation of devices with laminated parts, a dedicated method replaces the layered material in the laminate with a homogeneous medium whose magnetic properties have been specially adjusted.
Complex power and impedance calculationFor complex (phasor) calculations: impedance and power.
Coil winding constructionGenerates a DXF drawing from given coil data.
Iron loss coefficient calculationComputes core loss coefficients from a given data set.
DXF import conversionConverts a DXF file into a format compatible with QuickField's DXF import.
Exported field data visualizationQuickField can export field data as a text file; this online script visualizes the exported data.
Formula plottingPlots the corresponding 2D curve, to help you construct QuickField formulas.
Harmonic analysisPerforms harmonic analysis on input data of any kind. Data can be copied from a QuickField time chart or LabelMover results, and the amplitude and phase of the specified harmonic order are computed automatically.
Natural convection coefficient calculationGives the natural convection heat transfer coefficient for several predefined surface types.
Skin depth calculationComputes the penetration depth of the skin effect.
