<b>Betreff:</b> [Getdp] How to define a discontinuous interface condition<o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p>Hello Everyone, <o:p></o:p></p>
<p><o:p> </o:p></p>
<p>I have problem to define a Discontinuous Interface Condition. The basic structure is that there are two 3D cube 1 and 2 sharing a common interface and the 2D side view is like this:
<o:p></o:p></p>
<p>------------------------------- <o:p></o:p></p>
<p>| | | <o:p></o:p></p>
<p>| 1 | 2 | <o:p></o:p></p>
<p>| | | <o:p></o:p></p>
<p><o:p> </o:p></p>
<p>| | | <o:p></o:p></p>
<p>------------------------------- <o:p></o:p></p>
<p>For a static electric problem(laplace equation), given some boundary condition, and a interface resistance--which means that the potential does not continuous in the interface, I want to solve the potential phi.
<o:p></o:p></p>
<p>The phsics at the interface should be \Delta phi \cdot \hat{n} = phi_1-phi_2, where \hat{n} is the normal vector of the interface and phi_1 and phi_2 are the value of potential phi at the interface(actually extremely closing to the interface) from cube 1
and cube 2, respectively. <o:p></o:p></p>
<p>The problem is that I donot know how to the describe this boundary as a formulation, and I have searched the archive of this mail-list but didnot get good information.
<o:p></o:p></p>
<p>Can you give some suggestion on this kind of interface boundary condition? <o:p>
</o:p></p>
<p>Massive thanks in advance!! <o:p></o:p></p>
