			<content:encoded><![CDATA[<p>I am out of office the first half of the next week. I will give a talk on
&quot;Numerische Zeit&shy;integrations&shy;verfahren für gekoppelte Feld- und Netzwerk&shy;probleme&quot;
in the <a href="http://numerik.mathematik.uni-halle.de/oberseminar/">Oberseminar Numerische Mathematik</a> of the Martin-Luther-Universität Halle-Wittenberg on December, 6.</p>
<span id="more-1629"></span>
From the abstract:
<blockquote style="font-size: 11px">
In diesem Vortrag werden Mehrskalenverfahren für die schwachgekoppelte Simulation von räumlich-verteilten elektromagnetischen Bauteilen mit elektrischen Netzwerken besprochen. Wir betrachten Bauteile, die durch Maxwell&#8217;s partielle Differentialgleichungen (PDEs) und einigen zusätzlichen algebraischen Kopplungsgleichungen (AE) beschrieben werden, so dass das resultierende elektromagnetische Problem aus PDAEs besteht. Auf der anderen Seite wird die elektrische Schaltung direkt aus einem Netzwerkansatz heraus als System von differential-algebraischen Gleichungen modelliert. Die Kopplung von Netzwerk- und Feldmodellen erlaubt hier eine effiziente Nutzung des Mehrskalenverhaltens im Ort (multiscale). Eine typische Anwendung sind niederfrequente Bauteile wie Transformatoren oder Motoren, die durch gepulste Signale gesteuerte werden, so dass hier gleichzeitig Effekte auf verschiedenen Zeitskalen ablaufen (multirate). Die Struktur, Kopplung und der Index der semidiskreten Systeme werden analysiert und maßgeschneiderte Verfahren vorgestellt. Insbesondere werden Cosimulation und Bypassing-Verfahren, aber auch explizite Integratoren für das elektromagnetische Problem diskutiert. Wir zeigen analytisch und numerisch, dass die Methoden stabil und effizient arbeiten.

Comission</a>. 
The talk was on &#8216;Transient Magneto-Quasistatic Field Simulation Using Domain Decomposition with Semi-Implicit Time Integration&#8217;. This is a joint work together with <a href="http://www-num.math.uni-wuppertal.de/">Andreas Bartel</a> and <a href="http://tet.uni-wuppertal.de/">Markus Clemens</a> from the Lehrstuhl für Numerische Analysis und Angewandte Mathematik and the Lehrstuhl für Theoretische Elektrotechnik, Bergische Universität Wuppertal, respectively.</p>
<span id="more-1503"></span>

<p><b>From the abstract:</b></p>
<p>In this contribution semi-explicit time integration of the magneto-quasistatic approximation of Maxwell&#8217;s equations is discussed. Space-discretization of the eddy-current  problem results in a nonlinear differential-algebraic system. The eddy-current regions are described by (nonlinear) differential equations and the remainder (e.g. air) is typically modeled by a linear algebraic system. We apply a domain substructuring such that the conductive and nonconductive domains are treated separately by the time integrator. The conductive domain is solved explicitly in time such that parallelization can easily be exploited. The numerical stability of the explicit time integration scheme requires small time step sizes according to a Courant-Friedrich-Levi stability criterion, but at relatively low computational costs due to the explicit update scheme. Numerical results show the feasibility of this approach. In particular, a higher order half-explicit time integration scheme with extended stability region is shown to be very efficient.</p>

			<content:encoded><![CDATA[<p>A new journal article &#8220;Structural analysis of electrical circuits including magnetoquasistatic devices&#8221; (written together with <a href="http://www-num.math.uni-wuppertal.de/">Andreas Bartel</a> and <a href="http://www.mi.uni-koeln.de/~sbaumann/index.php">Sascha Baumanns</a>) is finally online.

<span id="more-1581"></span>
From the abstract:
<blockquote>Modeling electric circuits that contain magnetoquasistatic (MQS) devices leads to a coupled system of differential-algebraic equations (DAEs). In our case, the MQS device is described by the eddy current problem being already discretized in space (via edge-elements). This yields a DAE with a properly stated leading term, which has to be solved in the time domain. We are interested in structural properties of this system, which are important for numerical integration. Applying a standard projection technique, we are able to deduce topological conditions such that the tractability index of the coupled problem does not exceed two. Although index-2, we can conclude that the numerical difficulties for this problem are not severe due to a linear dependency on index-2 variables.</blockquote>
