New Vizimag 3.17 for visualizing magnetic fields is simple to use electromagnetic modelling software giving an analysis and simulation of field lines and flux density. A fast alternative to finite element and boundary element software, Vizimag includes a meter function to measure and plot magnetic flux density. Magnetic field animations can be created and a transformer design aid is included.
Full function list:
Transformer analysis: A manual mode calculates the parameters of a transformer equivalent circuit The model mode takes data from a Vizimag model and calculates flux coupling and inductance from a Vizimag simulation. Variable geometry and air coupled modes. The manual mode will remain working when the trial period is over.
Force function: The magnetic force on a selected object can be calculated with a single click. Available on most objects.
Flux density contours: A set of fixed, or user defined, contours can be plotted on the flux density display. The contours can be marked using the annotation function. Line width can be changed.
Annotation: The plot area can be annotated. The annotation is saved with the model.
Animation mode: Simple text script, syntax checking, error checking, full control of display modes and animation speed, plot B or H: magnitude, normal or tangential to plot line, export of plot data for each frame of an animation.
Magnetic models: rectangular, toroidal and curved magnets, solenoids and regions; triangular and circular regions, freeform magnets and solenoids, external fields.
Editing functions: Add, move, copy, rotate, flip, switch poles, size, zoom and pan, delete key, arrow key fine adjustment, grid scaling, direct dimension entry, keyboard shortcuts, undo/redo.
Inductance: the inductance of solenoids and toroids is estimated from the analysis result.
Calculator mode: The calculator mode allows the flux density of a single or multi-layer air-cored solenoid to be calculated anywhere on or off-axis. The calculation is from the theoretical equations and is accurate to several decimal places. this function remains working when the trial period is over.
Full graphical interface: toolbars, status readouts, B, Bx, By and angle read out.
Analysis meshes: up to 800 X 800.
Plot facility: options include log axis and titles. B or H, magnitude or normal or tangential to plot line. Integrals and averages are shown where appropriate.
Optional export of plot data in spreadsheet compatible format.
Option to export plot data for each frame of an animation in a multi-worksheet spreadsheet.
Simple relative units or full absolute units modes.
Snap to grid feature.
Automatic saving of an analysis run.
bmp, gif and jpg clipboard formats.
Field line and flux density displays.
Option to have wires enclosed in core material.
Models entered with a few mouse clicks.
Vizimag is designed for fast, intuitive modeling and calculation, and can be used by scientists and engineers, or as a teaching aid to demonstrate the principles of magnetic materials and circuits
