WEBVTT - Induction heating modelling with QuickField 00:00.000 --> 00:11.000 Hello and welcome to our webinar. Our topic today is simulation of the induction heating systems using QuickField FEA software. My name is Vladimir, and I will start now. 00:11.000 --> 00:21.000 Induction heating is a process of heating the conductive materials (usually metals or semiconductors) by the electric currents caused by the changing magnetic field. 00:21.000 --> 00:27.000 Field is usually generated by the inductor, which is essentially a coil placed around the heated media. 00:27.000 --> 00:37.000 Induction heating of long structures like rails (for surface hardening), or pipes (for welding from the sheet metal) often requires moving of the heated object through the stationary inductor. 00:37.000 --> 00:47.000 In reality, inductor is not just a simple coil, it is a very complicated piece of equipment which should be designed and manufactured by the experienced specialists. 00:47.000 --> 00:54.000 This webinar is a result of our cooperation with a leading company in this field – Selit S.R.L. who is also our customer. 00:54.000 --> 01:05.000 And I want to express our sincere gratitude to its Vice General Manager Davide Bernardi for many fruitful discussions and experience we gained by working on his models. 01:06.000 --> 01:17.000 Simulation of the induction heating system is not easy. In most simple case it requires both electromagnetic and heat transfer analysis. 01:17.000 --> 01:31.000 But electromagnetic and thermal parameters of materials involved may be highly dependent on the temperatures and field intensities. So these tasks may require non-linear Multiphysics coupling – which is really complicated. 01:31.000 --> 01:40.000 This slide shows you what should be included into the induction heating simulation process. As you see – there is a lot…. 01:40.000 --> 01:49.000 But our product- QuickField has a very simple front-end, but very powerful FEA engine inside, which supports many types of analysis. 01:50.000 --> 02:03.000 Today we will show you most effective methods of induction heating simulation using the basic set QuickField features and specially developed tools, which may be used as is or modified to better suit your practical tasks. 02:04.000 --> 02:18.000 For those who never used QuickField before - here you see a list of all analysis options available for the latest official release 6.6 and for the coming version 7.0 which is now available as Beta. 02:18.000 --> 02:29.000 They include AC, DC and Transient magnetics, Electrostatics, AC and DC conduction, Transient Electric analysis, Transient and Steady State heat transfer and mechanical stress analysis. 02:29.000 --> 02:46.000 They are bundled into three suites for Magnetic analysis, Electric analysis and Thermostructural analysis. All these formulations are available for 2D, and for 3D we now have Steady State Heat transfer, DC conduction and Electrostatics. 02:47.000 --> 02:59.000 For induction heating simulations you will most probably require AC Magnetic analysis and Static or Transient Heat Transfer analysis, which will be shown in the examples today. 02:59.000 --> 03:11.000 If the task requires more than one type of analysis - 2D modules of QuickField may be used separately or in some combinations, to perform the multiphysical coupled analysis. 03:11.000 --> 03:30.000 This slide shows possible types of combined analysis – bringing the electromagnetic losses as heat sources for thermal analysis, importing the thermal loads to stress analysis, using the electromagnetic forces in the mechanical stress analysis. 03:30.000 --> 03:49.000 For induction heating the coupling is very important, because the joule losses in the heated material should be calculated in the AC or Transient Magnetic problem, but the electromagnetic parameters are temperature dependent, so the multiphysical coupling of Magnetics and Heat Transfer analysis is essential. 03:50.000 --> 04:04.000 QuickField workflow is extremely simple. You need to specify the model geometry and build the Finite Element mesh in the Model Editor (from scratch, or starting from CAD geometry file import). 04:04.000 --> 04:16.000 You should define the physical properties and field sources in the Data Editor, and after running the automatic solving procedure – analyze the results using powerful interactive graphical postprocessors. 04:17.000 --> 04:31.000 Geometry of QuickField models may be chosen from the following classes: 2D plane-parallel or axisymmetrical, which is presented by an upper half of the axial cross-section. 04:31.000 --> 04:58.000 And for those types of analysis which are possible in 3D – geometry may be defined using the 3D extrusion from the planar sketch, or imported from the STEP file with 3D geometry created in CAD. 04:58.000 --> 05:12.000 Unique feature of QuickField is the existence of the full-features open object Application Programming interface, which allows interaction with QuickField FEA core for other applications, created in many programming environments. 05:12.000 --> 05:26.000 This allows using QuickField as a part of a larger simulation or control system, for automation of the repetitive tasks, optimization and anything where the manual interaction with FEA model is not sufficient. 05:27.000 --> 05:44.000 As I mentioned in the beginning, for Induction Heating simulation automation we developed a special tool, which represent a Microsoft Excel document with embedded VBA macros, interacting with QuickField using this technology. We will show it later in more details. 05:44.000 --> 05:57.000 Unique feature of QuickField, which makes it the tool of choice of many researchers and engineers around the world – its simplicity. We are proud to say that QuickField does not need any dedicated training. 05:57.000 --> 06:09.000 My colleague Alex will demonstrate it today in the live simulations of examples related to induction heating. Alex – please, continue!
