I.e. you would select the vertices in different orders depending on whether reflection, rotation etc is involved. Also I assume the boundaries will need to be topologically similar or perhaps identical. Otherwise I am not sure whether/how COMSOL deals with it.<br /> <br /> I think you need to select all the vertices in the boundary - not sure if you can get away with a subset.<br /> <br /> good luck<br /> Ozgur<br /> <br /> <div class="quote"><br /> Dear all,<br /> <br /> Could anybody explain me the real role of source and destination vertices in Periodic BC?<br /> <br /> Does the amount of selected vertices influences only on precision or I MUST select all of vertices of a boundary each time?<br /> <br /> Thanks in advance,<br /> Alex<br /> </div><br /> <br /> Wed, 17 Mar 2010 17:49:37 +0000 3940.1268848177.10261 http://www.comsol.eu/community/forums/general/thread/3940/#p10246 Dear all,<br /> <br /> Could anybody explain me the real role of source and destination vertices in Periodic BC?<br /> <br /> Does the amount of selected vertices influences only on precision or I MUST select all of vertices of a boundary each time?<br /> <br /> Thanks in advance,<br /> Alex Wed, 17 Mar 2010 14:04:28 +0000 3940.1268834668.10246
