WEBVTT - AC magnetic simulation with QuickField
00:00.000 --> 00:18.000
Hello and welcome. This is QuickField webinar dedicated to AC Magnetic analysis simulations. My name is Vladimir, and I will make a brief introduction to QuickField FEA analysis software. Then my colleague Alex will make live presentations explaining several QuickField AC Magnetic simulation examples.
00:18.000 --> 01:12.000
So what is QuickField. Our product – QuickField is a Finite Element simulation software with wide range of analysis options. They are grouped into three suits for magnetic analysis, electric analysis and thermostructural analysis and include MS, AC Magnetics, Transient Magnetics, Electrostatics, DC and AC conduction, Transient Electric field, Steady State and Transient Heat transfer, and also Stress analysis. All these types of analysis are available in plane-parallel or axisymmetrical 2D formulations, and Electrostatics, DC Conduction and Steady State Heat transfer also may perform full 3D analysis. We are working on implementing more 3D analysis modules now.
01:13.000 --> 01:45.000
In 2D you can perform not only individual simulations for various physical setups, but also multyphysic coupling, when the results of one simulation are automatically imported as input data into other analysis. This way you can take into account the electromagnetic effects, like joule heating, in thermal analysis, see the deformations caused by magnetic attraction, of stresses resulting from uneven heating.
01:45.000 --> 02:18.000
QuickField offers impressive set of analysis options but today we will discuss one of them – AC Magnetic Analysis. The AC magnetic analysis is a study of the magnetic fields caused by time-harmonic alternating source currents, and currents induced by time-harmonic magnetic fields (eddy currents). It is used to evaluate the proximity effects, calculate impedances, Joule losses, electromagnetic forces.
02:18.000 --> 02:38.000
As with any other type of simulations, QuickField workflow fo AC Magnetics is very straightforward. You need to specify the type of problem, define the model geometry, enter physical data and then solve the model and analyse the results.
02:39.000 --> 03:04.000
This slide shows the details of AC Magnetic problem setup You choose the model class (plane-parallel or axisymmetrical), choose length units and coordinate systems, specify the frequency value, choose the geometry and data file names, and if the FEA problem also includes the electric circuit – specify the corresponding circuit file name.
03:05.000 --> 03:24.000
Data for AC magnetics include material properties – magnetic permeabilities, conductivities, and temperatures of temperature-dependent conductive materials, current or voltage sources, boundary conditions and linear currents.
03:24.000 --> 03:42.000
In AC Magnetic analysis you can connect FEA simulation blocks using complicated electric circuits. Circuit description allows to specify connecting wires, resistors, capacitors, inductors, current and voltage sources.
03:42.000 --> 04:02.000
Results offered by AC Magnetic postprocessors include color field maps, local parameters in any point, plots and integrals calculated using user-specified contours.
04:02.000 --> 04:15.000
This slide shows options for field result presentations – as you see, selection is very impressive and most probably includes everything you may need to know about your model.
04:15.000 --> 04:40.000
Unique feature of QuickFIeld is its open object Application Programming Interface. You may interact with QuickField core functions and data structures from other Windows applications, including Microsoft Office, Matlab, our own parametric analysis tool LabelMover or any third-party tools or custom modules which expand QuickFIeld set of features.
04:40.000 --> 05:00.000
And most important – this diverse and rich set of analysis options is offered in e very simple and user friendly package, which does not require any specialized training.
