WEBVTT - Film heaters modelling with QuickField 00:00.000 --> 00:22.000 Hello and welcome to our webinar. Today we will speak about particular application which involves DC Conduction and Heat transfer (separately, or together) – simulation of the film heaters. My name is Vladimir, I will make a short introduction and then my colleague Alex will continue with live presentations of various simulation problems related to film heaters. 00:22.000 --> 00:40.000 Film heating technology utilizes joule heat generation by the currents flowing in the thin conductive films, attached to the non-conductive sheets which provide the electric insulation and heat dissipation. 00:40.000 --> 00:52.000 Conductors may be either glued to its surface, or produced using a printed board circuit technology. The analysis usually requires finding out the distribution of the heat power and temperatures for given heating element topology and cooling conditions. 00:52.000 --> 01:02.000 And taking into account considerable number of QuickField customers who deal with this – our tool is an effective instrument for film heating analysis. 01:02.000 --> 01:24.000 Let me start from the brief explaining what is QuickField. Our product is a FEA software for variety of field simulation tasks and extensive set of analysis modules, which are listed in this table. 01:24.000 --> 01:57.000 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. They are bundled into three suites for Magnetic analysis, Electric analysis and Thermo-structural analysis. All types of analysis are available for 2D, and for 3D we now have Steady State Heat transfer, DC conduction and Electrostatics. 01:59.000 --> 02:14.000 2D modules may be used separately or in some combinations, to perform the Multiphysics coupling. For film heaters we often need to import the joule heat distribution to the thermal model and then find the temperatures - QuickField has this option! 02:15.000 --> 02:40.000 This slide shows all possible types of combined analysis – in addition to bringing the electromagnetic losses as heat sources for thermal analysis, QuickField supports importing the thermal loads to stress analysis, using the electromagnetic forces in the mechanical stress analysis, and importing magnetic properties or temperatures from corresponding static to transient models 02:41.000 --> 03:07.000 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), 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. 03:08.000 --> 03:41.000 Geometry defined in QuickField may be chosen from the following classes- 2D plane-parallel or axisymmetrical, which is presented by an upper half of the axial cross-section, and for those types of analysis which are possible in 3D – geometry may be defined using the 3D extrusion from the planar sketch, or import of the STEP file with 3D geometry created in CAD. 03:42.000 --> 04:12.000 Unique feature of QuickField is the existence of a full-featured open object Application Programming interface, which allows interaction with QuickField FEA core for other applications, created in many programming environments. This is a way to go for using QuickField model as a part of a larger simulation or control system, for automation of the repetitive tasks, optimization and anything where the human graphical user interface is not sufficient. 04:15.000 --> 04:39.000 As you see – QuickField is a very powerful tool, which is surprisingly easy to use. We are proud to say that QuickField does not need any dedicated training. And now let us see how Alex proves this by his live presentations of QuickField models related to the film heating devices. Alex – please continue.
